2nd millennium
–
The second millennium was a period of time that began on January 1,1001 and ended on December 31,2000 of the Gregorian calendar. It was the period of one thousand years in the Anno Domini or Common Era. The Renaissance saw the beginning of the migration of humans from Europe, Africa. The interwoven international trade led to the formation of multi-national corporations, international business ventures reduced the impact of nationalism in popular thought. The world population doubled over the first seven centuries of the millennium, consequently, unchecked human activity had considerable social and environmental consequences, giving rise to extreme poverty, climate change and biotic crisis. The 2nd millennium was a period of time began on January 1,1001. It was the period of one thousand years in the Anno Domini or Common Era. The Julian calendar was used in Europe at the beginning of the millennium, so the end date is always calculated according to the Gregorian calendar, but the beginning date is usually according to the Julian calendar. Stephen Jay Gould argued that it is not possible to decide if the millennium ended on December 31,1999, or December 31,2000. The second millennium is perhaps more popularly thought of as beginning and ending a year earlier, thus starting at the beginning of 1000 and finishing at the end of 1999. Many public celebrations for the end of the millennium were held on December 31,1999 – January 1, the civilizations in this section are organized according to the UN geoscheme.

15th century
–
The 15th century was the century which spans the Julian years 1400 to 1500. In Europe, the 15th century is seen as the bridge between the Late Middle Ages, the Early Renaissance, and the Early modern period. Many technological, social and cultural developments of the 15th century can in retrospect be seen as heralding the European miracle of the following centuries, in religious history, the Roman Papacy was split in two parts in Europe for decades, until the Council of Constance. The division of the Catholic Church and the unrest associated with the Hussite movement would become factors in the rise of the Protestant Reformation in the following century. The event forced Western Europeans to find a new route, adding further momentum to what was the beginning of the Age of Discovery. Explorations by the Spanish and Portuguese led to European sightings of the Americas and these expeditions ushered in the era of the Portuguese and Spanish colonial empires. The fall of Constantinople led to the migration of Greek scholars and texts to Italy and these two events played key roles in the development of the Renaissance. The Spanish Reconquista leads to the fall of the Emirate of Granada by the end of the century, ending over seven centuries of Muslim rule. The Hundred Years War end with a decisive French victory over the English in the Battle of Castillon, financial troubles in England following the conflict results in the Wars of the Roses, a series of dynastic wars for the throne of England. The conflicts ends with the defeat of Richard III by Henry VII at the Battle of Bosworth Field, establishing the Tudor dynasty in the later part of the century. In Asia, under the rule of the Yongle Emperor, who built the Forbidden City and commanded Zheng He to explore the world overseas, tamerlane established a major empire in the Middle East and Central Asia, in order to revive the Mongol Empire.

The 16th century begins with the Julian year 1500 and ends with either the Julian or the Gregorian year 1600. It is regarded by historians as the century in which the rise of the West occurred, during the 16th century, Spain and Portugal explored the worlds seas and opened worldwide oceanic trade routes. In Europe, the Protestant Reformation gave a blow to the authority of the papacy. European politics became dominated by conflicts, with the groundwork for the epochal Thirty Years War being laid towards the end of the century. In Italy, Luca Pacioli published the first work ever on accounting, in United Kingdom, the Italian Alberico Gentili wrote the first book on public international law and divided secularism from canon law and Roman Catholic theology. In the Middle East, the Ottoman Empire continued to expand, with the Sultan taking the title of Caliph, China evacuated the coastal areas, because of Japanese piracy. Japan was suffering a civil war at the time.

Gregorian calendar
–
The Gregorian calendar is internationally the most widely used civil calendar. It is named after Pope Gregory XIII, who introduced it in October 1582, the calendar was a refinement to the Julian calendar involving a 0. 002% correction in the length of the year. The motivation for the reform was to stop the drift of the calendar with respect to the equinoxes and solstices—particularly the northern vernal equinox, transition to the Gregorian calendar would restore the holiday to the time of the year in which it was celebrated when introduced by the early Church. The reform was adopted initially by the Catholic countries of Europe, the last European country to adopt the reform was Greece, in 1923. Many countries that have used the Islamic and other religious calendars have come to adopt this calendar for civil purposes. The reform was a modification of a made by Aloysius Lilius. His proposal included reducing the number of years in four centuries from 100 to 97. Lilius also produced an original and practical scheme for adjusting the epacts of the moon when calculating the date of Easter. For example, the years 1700,1800, and 1900 are not leap years, but the years 1600 and 2000 are. The canonical Easter tables were devised at the end of the third century, when the vernal equinox fell either on 20 March or 21 March depending on the years position in the leap year cycle. As the rule was that the full moon preceding Easter was not to precede the equinox, the date was fixed at 21 March for computational purposes, the Gregorian calendar reproduced these conditions by removing ten days. To unambiguously specify a date, dual dating or Old Style, dual dating gives two consecutive years for a given date, because of differences in the starting date of the year, and/or to give both the Julian and the Gregorian dates. The Gregorian calendar continued to use the calendar era, which counts years from the traditional date of the nativity. This year-numbering system, also known as Dionysian era or Common Era, is the predominant international standard today, the Gregorian calendar is a solar calendar. A regular Gregorian year consists of 365 days, but as in the Julian calendar, in a leap year, in the Julian calendar a leap year occurs every 4 years, but the Gregorian calendar omits 3 leap days every 400 years. In the Julian calendar, this day was inserted by doubling 24 February. In the modern period, it has become customary to number the days from the beginning of the month, some churches, notably the Roman Catholic Church, delay February festivals after the 23rd by one day in leap years. Gregorian years are identified by consecutive year numbers, the cycles repeat completely every 146,097 days, which equals 400 years

Ab urbe condita
–
Ab urbe condita is a Latin phrase meaning from the founding of the City, traditionally dated to 753 BC. AUC is a system used by some ancient Roman historians to identify particular Roman years. Renaissance editors sometimes added AUC to Roman manuscripts they published, giving the impression that the Romans usually numbered their years using the AUC system. The dominant method of identifying Roman years in Roman times was to name the two consuls who held office that year, the regnal year of the emperor was also used to identify years, especially in the Byzantine Empire after 537 when Justinian required its use. The traditional date for the founding of Rome of 21 April 753 BC, was initiated by 1st century BC scholar Marcus Terentius Varro, the correctness of Varros calculation has not been confirmed but it is still used worldwide. From Emperor Claudius onwards, Varros calculation superseded other contemporary calculations, celebrating the anniversary of the city became part of imperial propaganda. Claudius was the first to hold magnificent celebrations in honour of the citys anniversary, hadrian and Antoninus Pius held similar celebrations, in 121 AD and 147/148 AD respectively. During 248 AD, Philip the Arab celebrated Romes first millennium, coins from his reign commemorate the celebrations. The Anno Domini year numbering was developed by a monk named Dionysius Exiguus in Rome during 525, in his Easter table the year 532 AD was equated with the regnal year 248 of Emperor Diocletian. It was later calculated that the year 1 AD corresponds to the Roman year 754 AUC, based on Varros epoch

Balinese saka calendar
–
The Balinese saka calendar is one of two calendars used on the Indonesian island of Bali. Unlike the 210-day pawukon calendar, it is based on the phases of the moon, based on a lunar calendar, the saka year comprises twelve months, or sasih, of 30 days each. The months are adjusted by allocating two lunar days to one day every 9 weeks. This day is called ngunalatri, Sanskrit for minus one night, the length of these months is calculated according to the normal 63-day cycle. Both sets of days are numbered 1 to 15, the first day of the year is usually the day after the first new moon in March. Note, however, that Nyepi falls on the first day of Kadasa, the calendar is 78 years behind the Gregorian calendar, and is calculated from the beginning of the Saka Era in India. It is used alongside the 210-day Balinese pawukon calendar, and Balinese festivals can be calculated according to either year, the Indian saka calendar was used for royal decrees as early as the ninth century CE. The same calendar was used in Java until Sultan Agung replaced it with the Javanese calendar in 1633, the Balinese Hindu festival of Nyepi, the day of silence, marks the start of the Saka year. Tilem Kepitu, the last day of the 7th month, is known as Siva Ratri, devotees stay up all night and meditate. There are another 24 ceremonial days in the Saka year, usually celebrated at Purnama, ISBN9813018496 Hobart, Angela, Ramseyer, Urs & Leeman, Albert The Peoples of Bali, Blackwell Publishers.

Bengali calendars
–
The Bengali Calendar or Bangla Calendar is a solar calendar used in the region of Bengal. A revised version of the calendar is the national and official calendar in Bangladesh, the New Year in the Bengali calendar is known as Pôhela Bôishakh. The Bengali Era or Anno Bengal, the Bengali year is 594 less than the AD or CE year in the Gregorian calendar if it is before Pôhela Bôishakh, the revised version of the Bengali calendar was officially adopted in Bangladesh in 1987. However, it is not followed in India where the traditional version continues to be followed due to occurrence of Hindu festivals based on a particular sidereal solar day. The Bengali calendar is a solar calendar, the calendar was developed by Alauddin Husain Shah, a Hussain Shahi sultan of Bengal by combining the lunar Islamic calendar with the solar calendar, prevalent in Bengal. All theories agree that the Mughal Emperor, Akbar was instrumental in promulgating the Bengali calendar, Akbar modified, developed and re introduced the Bengali Calendar in order to make tax collection easier in Bengal. The calendar was called as Tarikh-e-Elahi. Sources credit the idea to Alauddin Husain Shah, akbars royal astronomer Fathullah Shirazi developed the Bengali calendar, by synthesizing the Lunar Islamic and Solar calendars. The calendar started with the Islamic calendar value, but the Sanskrit month names were used from the earlier version, the distinctive characteristic of the Bengali year was that rather than being a lunar calendar, it was based on a union of the solar and lunar year. This was essentially a great promotion as the solar and lunar years were formulated in very diverse systems, primarily this calendar was named as Fasli Sôn and then Bônggabdô. The Bengali Year was launched on 1584 AD or 992 AH and this was the day that Akbar defeated Hemu in the clash of Panipat to ascend the throne. The month of Muharram in the year 963 AH was equal to the month of Boishakh in the Bengali calendar, in the Tarikh-e-Elahi version of the calendar, each day of the month had a separate name, and the months had different names from what they have now. The Bengali calendar consists of 6 seasons, known as Rreetu ঋতু or Kal কাল, hence after some centuries the months will shift far away from the actual seasons. But the new revised version of the Bengali calendar used in Bangladesh will continue to maintain the seasons on time as mentioned above. The Bengali Calendar incorporates the seven-day week as used by other calendars. The names of the days of the week in the Bengali Calendar are based on the Navagraha, the day begins and ends at sunrise in the Bengali calendar, unlike in the Gregorian calendar, where the day starts at midnight. Pôhela Bôishakh in West Bengal and other states of India with Bengali diaspora, is celebrated on 14/15 April of the Gregorian calendar, however, according to the revised version of the calendar, now followed in Bangladesh, Pôhela Bôishakh always falls on 14 April. It is not clear, from what ground they start counting of 1st Bengali calendar year from the 593AD, the length of a year is counted as 365 days, as in the Gregorian calendar

Berber calendar
–
The Berber calendar is the agricultural calendar traditionally used by Berbers. It is also known as the fellaḥi, the calendar is utilized to regulate the seasonal agricultural works. It is used in lieu of the Islamic calendar, a calendar considered ill-adapted for agriculture because it does not relate to seasonal cycles. The current Berber calendar is a legacy of the Roman province of Mauretania Caesariensis, the latter calendar was used in Europe before the adoption of the Gregorian calendar, with month names derived from Latin. Berber populations previously used various indigenous calendars, such as that of the Guanche autochthones of the Canary Islands, however, relatively little is known of these ancient calendrical systems. Not much is known about the division of time among the ancient Berbers, some elements of a pre-Islamic, and almost certainly a pre-Roman calendar, emerge from some medieval writings, analyzed by Nico van den Boogert. Some correspondences with the traditional Tuareg calendar suggest that in antiquity there existed, with degree of diffusion. According to a 17th-century manuscript by Tomás Marín de Cubas, they computed their year, called Acano and it began in summer, when the sun enters in Cancer, on June 21, at the first conjunction they celebrated nine festival days for the crop. The name of one month is known in the native language. It seems it was the month of the year, corresponding to August. Such a name, in case it was made up by something like *wen that of + smet, may correspond, in the list of medieval Berber month names, with the ninth and tenth months, but data are too scarce for this hypothesis to be deepened. The agricultural Berber calendar still in use is almost certainly derived from the Julian calendar, the only slight discrepancy lies in that the extra day in leap years is not usually added at the end of February, but at the end of the year. Jean Servier has doubted that the calendar descends directly from the Julian calendar of the Latin era, there are standard forms for the names of the Amazigh calendar. The table below provides the forms used in Morocco, Algeria and Tunisia. In some areas they may be different due to communication and manipulation by the government. Moreover, pronunciation differs according to the region, the coldest period is made up by 20 white nights, from 12 to 31 dujamber, and 20 black nights, beginning on the first day of yennayer, corresponding to the Gregorian 14 January. The first day of the year is celebrated in various ways in the different parts of North Africa, a widespread tradition is a meal with particular foods, which vary from region to region, but in many zones it is provided by the sacrifice of an animal. In Algeria, such a holiday is celebrated even by people who dont use the Berber calendar in daily life

Henry IV of England
–
Henry IV, also known as Henry of Bolingbroke, was King of England and Lord of Ireland from 1399 to 1413, and asserted the claim of his grandfather, Edward III, to the Kingdom of France. Henry was born at Bolingbroke Castle in Lincolnshire, one of Henrys elder sisters, Philippa of Lancaster, married John I of Portugal, and the other, Elizabeth, was the mother of John Holland, 2nd Duke of Exeter. His younger half-sister Catherine, the daughter of his fathers second wife and he also had four half-siblings by Katherine Swynford, originally his sisters governess, then his fathers longstanding mistress, and later his third wife. These four children were given the surname Beaufort after a castle their father held in Champagne, Henrys relationship with his stepmother, Katherine Swynford, was a positive one, but his relationship with the Beauforts varied. In youth he seems to have close to all of them. His brother-in-law Ralph Neville remained one of his strongest supporters, and so did his eldest half-brother John Beaufort, Thomas Swynford, a son from Katherines first marriage to Sir Hugh Swynford, was another loyal companion. Thomas was Constable of Pontefract Castle, where King Richard II is said to have died, Henrys half-sister Joan Beaufort through his fathers relationship with Katherine Swynford was the grandmother of Edward IV and Richard III. Joan had married Ralph Neville, the 1st Earl of Westmorland, when their daughter Cecily married Richard Plantagenet, the 3rd Duke of York, and had several offspring, including Edward IV and Richard III, Joan became the grandmother of two York kings of England. Henry experienced a rather more inconsistent relationship with King Richard II than his father had, first cousins and childhood playmates, they were admitted together to the Order of the Garter in 1377, but Henry participated in the Lords Appellants rebellion against the king in 1387. After regaining power, Richard did not punish Henry, although he did execute or exile many of the rebellious barons. In fact, Richard elevated Henry from Earl of Derby to Duke of Hereford, Henry spent the full year of 1390 supporting the unsuccessful siege of Vilnius by Teutonic Knights with his 300 fellow knights. During this campaign he bought 300 captured Lithuanian princes and then took them back to England. Henrys second expedition to Lithuania in 1392 illustrates the benefits to the Order of these guest crusaders. His small army consisted of over 100 men, including longbow archers and six minstrels, despite the efforts of Henry and his English crusaders, two years of attacks on Vilnius proved fruitless. In 1392–93 Henry undertook a pilgrimage to Jerusalem, where he made offerings at the Holy Sepulchre, later he vowed to lead a crusade to free Jerusalem from the infidel, but he died before this could be accomplished. The relationship between Henry Bolingbroke and the king met with a second crisis, in 1398, a remark by Bolingbroke regarding Richard IIs rule was interpreted as treason by Thomas de Mowbray, 1st Duke of Norfolk. The two dukes agreed to undergo a duel of honour at Gosford Green near Caludon Castle, Mowbrays home in Coventry, yet before the duel could take place, Richard II decided to banish Henry from the kingdom to avoid further bloodshed. Mowbray himself was exiled for life, John of Gaunt died in 1399

Buddhist calendar
–
While the calendars share a common lineage, they also have minor but important variations such as intercalation schedules, month names and numbering, use of cycles, etc. In Thailand, the name Buddhist Era is a numbering system shared by the traditional Thai lunisolar calendar. The Southeast Asian lunisolar calendars are based on an older version of the Hindu calendar. One major difference is that the Southeast Asian systems, unlike their Indian cousins, instead, they employ their versions of the Metonic cycle. However, since the Metonic cycle is not very accurate for sidereal years, yet no coordinated structural reforms of the lunisolar calendar have been undertaken. Today, the traditional Buddhist lunisolar calendar is used mainly for Theravada Buddhist festivals, the Thai Buddhist Era, a renumbered Gregorian calendar, is the official calendar in Thailand. The Burmese calendar in turn was based on the original Surya Siddhanta system of ancient India, one key difference with Indian systems is that the Burmese system has followed a variation of the Metonic cycle. It is unclear from where, when or how the Metonic system was introduced, the Burmese system, and indeed the Southeast Asian systems, thus use a strange combination of sidereal years from Indian calendar in combination with the Metonic cycle better for tropical years. In all Theravada traditions, the epochal year 0 date was the day in which the Buddha attained parinibbāna. However, not all agree on when it actually took place. In Burmese Buddhist tradition, it was 13 May 544 BCE, but in Thailand, it was 11 March 545 BCE, the date which the current Thai lunisolar and solar calendars use as the epochal date. In Myanmar, the difference between BE and CE can be 543 or 544 for CE dates, and 544 or 543 for BCE dates, in Sri Lanka, the difference between BE and CE is 544. The calendar recognizes two types of months, synodic month and sidereal month, the Synodic months are used to compose the years while the 27 lunar sidereal days, alongside the 12 signs of the zodiac, are used for astrological calculations. The days of the month are counted in two halves, waxing and waning, the 15th of the waxing is the civil full moon day. The civil new moon day is the last day of the month, because of the inaccuracy of the calendrical calculation systems, the mean and real New Moons rarely coincide. The mean New Moon often precedes the real New Moon, as the Synodic lunar month is approximately 29.5 days, the calendar uses alternating months of 29 and 30 days. Various regional versions of Chula Sakarat/Burmese calendar existed across various regions of mainland Southeast Asia, unlike Cambodian and Burmese systems, Kengtung, Lan Na, Lan Xang and Sukhothai systems refer to the months by numbers, not by names. The Buddhist calendar is a calendar in which the months are based on lunar months

Byzantine calendar
–
The Byzantine calendar, also called Creation Era of Constantinople or Era of the World, was the calendar used by the Eastern Orthodox Church from c.691 to 1728 in the Ecumenical Patriarchate. It was also the official calendar of the Byzantine Empire from 988 to 1453, the calendar was based on the Julian calendar, except that the year started on 1 September and the year number used an Anno Mundi epoch derived from the Septuagint version of the Bible. Its year one, the date of creation, was September 1,5509 BC. It is not known who invented the World era and when, nevertheless, the first appearance of the term is in the treatise of a certain monk and priest, Georgios, who mentions all the main variants of the World Era in his work. He also already regards it as the most convenient for the Easter computus and this date underwent minor revisions before being finalized in the mid-7th century, although its precursors were developed c. By the second half of the 7th century, the Creation Era was known in Western Europe, by the late 10th century around AD988, when the era appears in use on official government records, a unified system was widely recognized across the Eastern Roman world. The era was ultimately calculated as starting on September 1, Thus historical time was calculated from the creation, and not from Christs birth, as in the west. The Eastern Church avoided the use of the Anno Domini system of Dionysius Exiguus, meanwhile, as Russia received Orthodox Christianity from Byzantium, she inherited the Orthodox Calendar based on the Byzantine Era. After the collapse of the Byzantine Empire in 1453, the era continued to be used by Russia and it was only in AD1700 that the Byzantine World Era in Russia was changed to the Julian Calendar by Peter the Great. It still forms the basis of traditional Orthodox calendars up to today, September AD2000 began the year 7509 AM. Both of these early Christian writers, following the Septuagint version of the Old Testament, the Alexandrian Era developed in AD412, was the precursor to the Byzantine Era. After the initial attempts by Hippolytus, Clement of Alexandria and others, the Alexandrine monk Panodorus reckoned 5904 years from Adam to the year AD412. This created the Alexandrian Era, whose first day was the first day of the proleptic Alexandrian civil year in progress,29 August 5493 BC, with the ecclesiastical year beginning on 25 March 5493 BC. This system presents in a sort of way the mystical coincidence of the three main dates of the worlds history, the beginning of Creation, the Incarnation. It was the first day of the year in the medieval Julian calendar, the Alexandrian Era of March 25,5493 BC was adopted by church fathers such as Maximus the Confessor and Theophanes the Confessor, as well as chroniclers such as George Syncellus. Its striking mysticism made it popular in Byzantium especially in monastic circles and it had for its basis a chronological list of events extending from the creation of Adam to the year AD627. The chronology of the writer is based on the figures of the Bible, St. John Chrysostom says in his Homily On the Cross and the Thief, that Christ, opened for us today Paradise, which had remained closed for some 5000 years. St. Isaac the Syrian writes in a Homily that before Christ, for five thousand five hundred

Chinese calendar
–
Traditional Chinese calendar is a lunisolar calendar which reckons years, months and days according to astronomical phenomena. It is used for activities in China and overseas Chinese communities. It depictures and lists the dates of traditional Chinese holidays, and guides Chinese people in selecting the most auspicious days for weddings, funerals, moving, in the Chinese calendar, the days begin and end at midnight. The months begin on the day with the dark moon, the years begin with the dark moon near the midpoint between winter solstice and spring equinox. The solar terms are the important components of the Chinese calendar, in a month, there are one to three solar terms. The currently used traditional Chinese calendar is the end result of centuries of evolution, many astronomical and seasonal factors were added by ancient scientists, and people can reckon the date of natural phenomena such as the moon phase and tide upon the Chinese calendar. The Chinese calendar has over 100 variants, whose characteristics reflect the evolutionary path. As with Chinese characters, different variants are used in different parts of the Chinese cultural sphere, calendars in Mongolia and Tibet have absorbed elements from the Chinese calendar and elements from other systems, but they are not direct descendants of the Chinese calendar. The official calendar in China is the Gregorian calendar, but the traditional Chinese calendar still plays an important role there. The Chinese calendar is known officially as the Rural Calendar, but is referred to by other names, such as the Former Calendar. The Chinese calendar preserves traditional East Asian culture, although the month sequences of Chinese calendar is decided by the solar term, the Chinese calendar is not an agriculture calendar. The Chinese calendar has greatly influenced the traditional calendars around Asia, the calendar has a year, month and date frame. The key elements are the day, synodic month and solar year, the Chinese calendar is a lunisolar calendar, similar to the Hindu and Hebrew calendars. The concepts in the Chinese, Hindu, and Hebrew calendars, day, in the Chinese calendar, a day starts from the midnight, in the Hindu calendars, a day starts from sunrise, and in the Hebrew calendar, a day starts from sunset. Month, the time is based on the obliquity of the moon path, a month is about 29 17/32 days. Phase, 1/30 month, 12° obliquity of the moon path, a unique concept of dating method in the Hindu calendar, a phase is about 63/64 day, which derived out the 64 divinatory symbols. Date, the day number in a month, in the Chinese and Hebrew calendars, days are numbered in sequence from 1 to 29 or 30, and in the Hindu calendars, the days are numbered according to the number of the phase in the days. In the Hindu calendars, some dates may be vacant, Year, the time based on the earths revolution

Rooster (zodiac)
–
The Rooster is one of the 12-year cycle of animals which appear in the Chinese zodiac related to the Chinese calendar. The Year of the Rooster is represented by the Earthly Branch character 酉, the name is also translated into English as Cock or Chicken. Rooster is the only bird included in the Chinese zodiac, however, the Chinese term is more generic, as it applies to barnyard fowl of either sex. In the Tibetan zodiac and the Nepalese Gurung zodiac, the more generic bird is in place instead of the Rooster

Ethiopian calendar
–
A seven- to eight-year gap between the Ethiopian and Gregorian calendars results from an alternate calculation in determining the date of the Annunciation. Like the Coptic calendar, the Ethiopic calendar has twelve months of 30 days plus five or six epagomenal days, the Ethiopian months begin on the same days as those of the Coptic calendar, but their names are in Geez. The sixth epagomenal day is added every four years without exception on August 29 of the Julian calendar, thus the first day of the Ethiopian year,1 Mäskäräm, for years between 1900 and 2099, is usually September 11. It, however, falls on September 12 in years before the Gregorian leap year, in the Gregorian year 2015, the Ethiopian calendar year 2008 begins on September 12, rather than September 11, on account of this additional epagomenal day occurring every four years. It occurs on September 11 in the Gregorian calendar, except for the following a leap year. The Ethiopian calendar year 1998 Amätä Məhrät began on September 11,2005, however, the Ethiopian years 1996 and 1992 began on September 12,2003 and 1999, respectively. This date correspondence applies for the Gregorian years 1900 to 2099, as the Gregorian year 2000 is a leap year, the current correspondence lasts two centuries instead. 400, thus its first civil year began seven months earlier on August 29, meanwhile, Europeans eventually adopted the calculations made by Dionysius Exiguus in AD525 instead, which placed the Annunciation eight years earlier than had Annianus. This causes the Ethiopian year number to be eight years less than the Gregorian year number from January 1 until September 10 or 11, in the past, a number of other eras for numbering years were also widely used in Ethiopia and the Kingdom of Aksum. Respective to the Gregorian and Julian New Years Days,3 1/2 to four months later and it is also because 532 is the product of the Metonic cycle of 19 years and the solar cycle of 28 years. Around AD400, an Alexandrine monk called Panodoros fixed the Alexandrian Era, after the 6th century AD, the era was used by Egyptian and Ethiopian chronologists. The twelfth 532-year-cycle of this era began on 29 August AD360, bishop Anianos preferred the Annunciation style as New Years Day,25 March. Thus he shifted the Panodoros era by about six months, to begin on 25 March 5492 BC, in the Ethiopian calendar this was equivalent to 15 Magabit 5501 B. C. The Anno Mundi era remained in usage until the late 19th century, the four-year leap-year cycle is associated with the four Evangelists, the first year after an Ethiopian leap year is named in honour of John, followed by the Matthew-year and then the Mark-year. The year with the sixth day is traditionally designated as the Luke-year. There are no exceptions to the four-year leap-year cycle, like the Julian calendar and these dates are valid only from March 1900 to February 2100. This is because 1900 and 2100 are not leap years in the Gregorian calendar, while they are leap years in the Ethiopian calendar, meaning dates before 1900. The Ethiopian Calendar, Appendix IV, C.

Hebrew calendar
–
The Hebrew or Jewish calendar is a lunisolar calendar used today predominantly for Jewish religious observances. It determines the dates for Jewish holidays and the public reading of Torah portions, yahrzeits. The present Hebrew calendar is the product of evolution, including a Babylonian influence, when to add it was based on observation of natural agriculture-related events in Israel. Through the Amoraic period and into the Geonic period, this system was displaced by the mathematical rules used today. The principles and rules were codified by Maimonides in the Mishneh Torah in the 12th century. Maimonides work also replaced counting years since the destruction of the Temple with the modern creation-era Anno Mundi, the era used since the Middle Ages is the Anno Mundi epoch. As with Anno Domini, the words or abbreviation for Anno Mundi for the era should properly precede the date rather than follow it, AM5777 began at sunset on 2 October 2016 and will end at sunset on 20 September 2017. The Jewish day is of no fixed length, the Jewish day is modeled on the reference to. there was evening and there was morning. In the creation account in the first chapter of Genesis, based on the classic rabbinic interpretation of this text, a day in the rabbinic Hebrew calendar runs from sunset to the next sunset. In most populated parts of the world this is always approximately 24 standard hours, halachically, a day ends and a new one starts when three stars are visible in the sky. The time between sunset and the time when the three stars are visible is known as bein hashmashot, and there are differences of opinion as to which day it falls into for some uses. This may be relevant, for example, in determining the date of birth of a child born during that gap, there is no clock in the Jewish scheme, so that the local civil clock is used. The civil clock is used only as a reference point – in expressions such as, Shabbat starts at. In Judaism, an hour is defined as 1/12 of the time from sunrise to sunset, so, during the winter, an hour can be less than 60 minutes. This proportional hour is known as a shaah zmanit, a Jewish hour is divided into 1080 halakim or parts. A part is 3⅓ seconds or 1/18 minute, the ultimate ancestor of the helek was a small Babylonian time period called a barleycorn, itself equal to 1/72 of a Babylonian time degree. These measures are not generally used for everyday purposes, instead of the international date line convention, there are varying opinions as to where the day changes. One opinion uses the antimeridian of Jerusalem, the weekdays start with Sunday and proceed to Saturday, Shabbat

Hindu calendar
–
Hindu calendar is a collective term for the various lunisolar calendars traditionally used in Hinduism. They adopt a similar underlying concept for timekeeping, but differ in their emphasis to moon cycle or the sun cycle, the names of months. A Hindu calendar is referred to as Panchanga. The ancient Hindu calendar is similar in design to the Jewish calendar. Early Buddhist communities of India adopted the ancient Indian calendar, later Vikrami calendar, Buddhist festivals continue to be scheduled according to a lunar system. The Buddhist calendar and the traditional calendars of Cambodia, Laos, Myanmar, Sri Lanka. Similarly, the ancient Jainism traditions have followed the lunisolar system as the Hindu calendar for festivals, texts. However, the Buddhist and Jaina timekeeping systems have attempted to use the Buddha, the Hindu calendar is also important to the practice of Hindu astrology and zodiac system, most of which it adopted from Greece, in centuries after the arrival of Alexander the Great. The Indian national calendar or Saka calendar was introduced in 1952 based on the traditional Hindu calendars and this study was one of the six ancient Vedangas, or ancillary science connected with the Vedas – the scriptures of Hinduism. The ancient Indian culture developed a time keeping methodology and calendars for Vedic rituals. David Pingree has proposed that the field of timekeeping in Jyotisha may have derived from Mesopotamia during the Achaemenid period. Ohashi states that this Vedanga field developed from actual astronomical studies in ancient India, timekeeping as well as the nature of solar and moon movements are mentioned in Vedic texts. For example, Kaushitaki Brahmana chapter 19.3 mentions the shift in the location of the sun towards north for 6 months. The Vikrami calendar is named after king Vikramaditya and starts in 57 BCE, Hindu scholars attempted to keep time by observing and calculating the cycles of sun, moon and the planets. These texts present Surya and various planets and estimate the characteristics of the respective planetary motion, other texts such as Surya Siddhanta dated to have been complete sometime between the 5th century and 10th century present their chapters on various planets with deity mythologies. The manuscripts of texts exist in slightly different versions, present Surya- and planets-based calculation. These vary in their data, suggesting that the text were open and they tracked the solar year by observing the entrance and departure of surya in the constellation formed by stars in the sky, which they divided into 12 intervals of 30 degrees each. Like other ancient human cultures, Hindus innovated a number of systems of which intercalary months became most used, as their calendar keeping and astronomical observations became more sophisticated, the Hindu calendar became more sophisticated with complex rules and greater accuracy

Vikram Samvat

Vikram Samvat Nepali, नेपाली पात्रो, Listen ) is an era used in India and Nepal, just like the Christian era started in 1 CE. The Vikram Samvat started in 58/57 BCE in southern and 57/56 BCE in northern systems of Hindu calendar, the era is named after king Vikramaditya. The Vikram Samvat calendar is 56.7 years ahead of the solar Gregorian calendar, for example, the year 2073 BS began in 2016 CE and will end in 2017 CE. The new year begins with the first day of month Baishakh, the first day of the new year is passionately celebrated in a historical carnival that takes place every year in Bhaktapur, called Bisket Jatra. The Rana rulers of Nepal made it their official calendar, there have been calls for the Vikram Samvat to replace Saka as Indias official calendar. The classical Vikram Samvat uses lunar months and solar sidereal years, because 12 months do not match a sidereal year exactly, correctional months are added or occasionally subtracted. A Tithi or lunar day is defined as the time it takes for the angle between the moon and the Sun to increase by 12°. Tithis begin at varying times of day and vary in duration from approximately 19 to approximately 26 hours, a Paksa or lunar fortnight consists of 15 tithis. According to popular tradition, the legendary king Vikramaditya of Ujjain established the Vikrama Samvat era after defeating the Śakas. Kalakacharya Kathanaka by the Jain sage Mahesarasuri gives the account, Gandharvasena, the then-powerful king of Ujjain, abducted a nun called Sarasvati. The enraged monk sought the help of the Śaka ruler King Sahi in Sistan, despite heavy odds but aided by miracles, the Śaka king defeated Gandharvasena and made him a captive. Sarasvati was repatriated, although Gandharvasena himself was forgiven, the defeated king retired to the forest, where he was killed by a tiger. His son, Vikramaditya, being brought up in the forest, had to rule from Pratishthana, later on, Vikramaditya invaded Ujjain and drove away the Śakas. To commemorate this event, he started a new era called the Vikrama era, the Ujjain calendar started around 56-58 BCE, and the subsequent Shaka era calendar was started in 78 CE at Pratishthana. The association of the era beginning in 57 BCE with Vikramaditya is not found in any source before the 9th century CE, the earlier sources call this era by various names, including Kṛṭa, Kritaa, the era of the Malava tribe, or simply, Samvat. The earliest known inscription that calls the era Vikrama is from 842 CE and this inscription of Chauhana ruler Chandamahasena was found at Dholpur, and is dated Vikrama Samvat 898, Vaishakha Shukla 2, Chanda. The earliest known inscription that associates this era with a king called Vikramaditya is dated 971 CE, the earliest literary work that connects the era to Vikramaditya is Subhashita-Ratna-Sandoha by the Jain author Amitagati. V. A. Smith and D. R. Bhandarkar believed that Chandragupta II adopted the title Vikramaditya, earlier, some scholars believed that the Vikrama Samavat corresponded to the Azes era of the Indo-Scythian king King Azes

Indian national calendar
–
The Indian national calendar, sometimes called the Saka calendar, is the official civil calendar in use in India along with the Vikram Samvat calendar. It is used, alongside the Gregorian calendar, by The Gazette of India, in broadcasts by All India Radio and in calendars. The Saka calendar is used in Java and Bali among Indonesian Hindus. Nyepi, the Day of Silence, is a celebration of the Saka new year in Bali, nepals Nepal Sambat evolved from the Saka calendar. The term may also refer to the Hindu calendar, the Saka era is also commonly used by other calendars. The calendar months follow the signs of the tropical zodiac rather than the sidereal zodiac normally used with Hindu calendar, in leap years, Chaitra has 31 days and starts on March 21 instead. The months in the first half of the year all have 31 days, the names of the months are derived from older, Hindu lunisolar calendars, so variations in spelling exist, and there is a possible source of confusion as to what calendar a date belongs to. Years are counted in the Saka Era, which starts its year 0 in the year 78 of the Common Era. To determine leap years, add 78 to the Saka year - if the result is a year in the Gregorian calendar. Its structure is like the Persian calendar, despite this effort, local variations based on older sources such as the Surya Siddhanta may still exist. Senior Indian Astrophysicist Meghnad Saha was the head of the Calendar Reform Committee under the aegis of the Council of Scientific, other members of the Committee were, A. C. Banerjee, K. K. Daftari, J. S. Karandikar, Gorakh Prasad, R. V. Vaidya and it was Saha’s effort, which led to the formation of the Committee. The task before the Committee was to prepare an accurate calendar based on scientific study, the Committee had to undertake a detailed study of different calendars prevalent in different parts of the country. The task was complicated by the fact that religion and local sentiments were integral to those calendars. Indias first prime minister, Jawaharlal Nehru, in his preface to the Report of the Committee, published in 1955, wrote, “They represent past political divisions in the country…. ”Usage started officially at Chaitra 1,1879, Saka Era, or March 22,1957, Dionysian Era. However, government officials seem to ignore the New Years Day of this calendar in favour of the religious calendar. Mapping Time, The Calendar and its History by E.

Kali Yuga
–
Kali Yuga is the last of the four stages the world goes through as part of the cycle of yugas described in the Sanskrit scriptures, within the present Mahayuga. The other ages are called Satya Yuga, Treta Yuga, Kali Yuga is associated with the demon Kali. The Kali of Kali Yuga means strife, discord, quarrel or contention, according to Puranic sources, Krishnas departure marks the end of Dvapara Yuga and the start of Kali Yuga, which is dated to 17/18 February 3102 BCE. According to the Surya Siddhanta, Kali Yuga began at midnight on 18 February 3102 BCE and this is also considered the date on which Lord Krishna left the earth to return to his heavenly abode. This information is placed at the temple of Bhalka, the place of this incident, according to the astronomer and mathematician Aryabhatta the Kali Yuga started in 3102 BCE. He finished his book “Aryabhattiya” in 499 CE, in which he gives the year of the beginning of Kali Yuga. He writes that he wrote the book in the year 3600 of the Kali Age at the age of 23. As it was the 3600th year of the Kali Age when he was 23 years old, and given that Aryabhatta was born in 476 CE, according to KD Abhyankar, the starting point of Kaliyuga is an extremely rare planetary alignment, which is depicted in the Mohenjo-Daro seals. Going by this alignment the year 3102 BCE is slightly off, the actual date for this alignment is February 7 of 3104 BCE. There is also sufficient proof to believe that Vrdhha Garga knew of precession at least by 500 BCE, Garga had calculated the rate of precession to within 30% of what the modern scholars estimate. The Kali Yuga is thought by some authors to last 6480 years although other durations have been proposed, hindus believe that human civilization degenerates spiritually during the Kali Yuga, which is referred to as the Dark Age because in it people are as far away as possible from God. Hinduism often symbolically represents morality as an indian bull, in Satya Yuga, the first stage of development, the bull has four legs, but in each age morality is reduced by one quarter. By the age of Kali, morality is reduced to only a quarter of that of the golden age, the Mahabharata War and the decimation of Kauravas thus happened at the Yuga-Sandhi, the point of transition from one yuga to another. A discourse by Markandeya in the Mahabharata identifies some of the attributes of Kali Yuga, in relation to rulers, it lists, Rulers will become unreasonable, they will levy taxes unfairly. Rulers will no longer see it as their duty to promote spirituality, or to protect their subjects, people will start migrating, seeking countries where wheat and barley form the staple food source. (Srimad-Bhagavatam With regard to relationships, Markandeyas discourse says, Avarice. Humans will openly display animosity towards each other, people will have thoughts of murder with no justification and will see nothing wrong in that. Lust will be viewed as acceptable and sexual intercourse will be seen as the central requirement of life

Islamic calendar
–
The Islamic, Muslim, or Hijri calendar is a lunar calendar consisting of 12 months in a year of 354 or 355 days. It is used to date events in many Muslim countries and it is also used by Muslims to determine the proper days of Islamic holidays and rituals, such as the annual period of fasting and the proper time for the pilgrimage to Mecca. The Islamic calendar employs the Hijri era whose epoch was retrospectively established as the Islamic New Year of AD622, during that year, Muhammad and his followers migrated from Mecca to Yathrib and established the first Muslim community, an event commemorated as the Hijra. In the West, dates in this era are usually denoted AH in parallel with the Christian, in Muslim countries, it is also sometimes denoted as H from its Arabic form. In English, years prior to the Hijra are reckoned as BH, the current Islamic year is 1438 AH. In the Gregorian calendar,1438 AH runs from approximately 3 October 2016 to 21 September 2017, four of the twelve Hijri months are considered sacred, Rajab, and the three consecutive months of Dhū al-Qa‘dah, Dhu al-Ḥijjah and Muḥarram. As the lunar calendar lags behind the solar calendar by about ten days every gregorian year, the cycle repeats every 33 lunar years. Each month of the Islamic calendar commences on the birth of the new lunar cycle, traditionally this is based on actual observation of the crescent marking the end of the previous lunar cycle and hence the previous month, thereby beginning the new month. Consequently, each month can have 29 or 30 days depending on the visibility of the moon, astronomical positioning of the earth and weather conditions. However, certain sects and groups, most notably Dawoodi Bohra Muslims and Shia Ismaili Muslims, use a tabular Islamic calendar in which odd-numbered months have thirty days, in Arabic, the first day of the week corresponds with Sunday of the planetary week. The Islamic weekdays, like those in the Hebrew and Baháí calendars, the Christian liturgical day, kept in monasteries, begins with vespers, which is evening, in line with the other Abrahamic traditions. Christian and planetary weekdays begin at the following midnight, Muslims gather for worship at a mosque at noon on gathering day which corresponds with Friday. Thus gathering day is regarded as the weekly day of rest. A few others have adopted the Saturday-Sunday weekend while making Friday a working day with a midday break to allow time off for worship. Inscriptions of the ancient South Arabian calendars reveal the use of a number of local calendars, at least some of these calendars followed the lunisolar system. For Central Arabia, especially Mecca, there is a lack of epigraphical evidence, both al-Biruni and al-Masudi suggest that the Ancient Arabs used the same month names as the Muslims, though they also record other month names used by the pre-Islamic Arabs. Nevertheless, the Islamic position equating Nisan with Dhū al-Ḥijja has prevailed, for a comparison between the Islamic and pre-Islamic months, see Islamic and Jahili months. The Islamic tradition is unanimous in stating that Arabs of Tihamah, Hejaz, the forbidden months were four months during which fighting is forbidden, listed as Rajab and the three months around the pilgrimage season, Dhu al-Qa‘dah, Dhu al-Hijjah, and Muharram

Japanese calendar
–
Japanese calendar types have included a range of official and unofficial systems. At present, Japan uses the Gregorian calendar together with year designations stating the year of the reign of the current Emperor, the lunisolar Chinese calendar was introduced to Japan via Korea in the middle of the sixth century. After that, Japan calculated its calendar using various Chinese calendar procedures, but in 1873, as part of Japans Meiji period modernization, a calendar based on the solar Gregorian calendar was introduced. In Japan today, the old Chinese calendar is virtually ignored, celebrations of the Lunar New Year are thus limited to Chinese, Japan has had more than one system for designating years. Including The Chinese sexagenary cycle was introduced into Japan. It was often used together with era names, as in the 1729 Ise calendar shown above, now, though, the cycle is seldom used except around New Years. The era name system was introduced from China, and has been in continuous use since AD701. Each Emperors reign begins a new era, before 1868 era names were also declared for other reasons. Nengō are the means of dating years in Japan. It is also in use in private and personal business. The Japanese imperial year or kigen 紀元 is based on the date of the founding of Japan by Emperor Jimmu in 660 BC. It was first used in the calendar in 1873. However, it never replaced era names, and since World War II has been abandoned, the Western Common Era system has gradually come into common use since the Meiji period. Now, most people know it, as well as era names, the official dating system known as nengō 年号, strictly speaking, gengō 元号, has been in use since the late 7th century. Years are numbered within eras, which are named by the reigning Emperor, the nengō system remains in wide use, especially on official documents and government forms. The imperial year system was used from 1872 to the Second World War, Imperial year 1 was the year when the legendary Emperor Jimmu founded Japan –660 BC according to the Gregorian Calendar. Usage of kōki dating can be a nationalist signal, pointing out that the history of Japans imperial family is longer than that of Christianity, kōki 2600 was a special year. The 1940 Summer Olympics and Tokyo Expo were planned as anniversary events, the Japanese naval Zero Fighter was named after this year
