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

William the Conqueror
–
William I, usually known as William the Conqueror and sometimes William the Bastard, was the first Norman King of England, reigning from 1066 until his death in 1087. A descendant of Rollo, he was Duke of Normandy from 1035 onward, after a long struggle to establish his power, by 1060 his hold on Normandy was secure, and he launched the Norman conquest of England six years later. The rest of his life was marked by struggles to consolidate his hold over England and his continental lands, William was the son of the unmarried Robert I, Duke of Normandy, by Roberts mistress Herleva. His illegitimate status and his youth caused some difficulties for him after he succeeded his father, during his childhood and adolescence, members of the Norman aristocracy battled each other, both for control of the child duke and for their own ends. In 1047 William was able to quash a rebellion and begin to establish his authority over the duchy and his marriage in the 1050s to Matilda of Flanders provided him with a powerful ally in the neighbouring county of Flanders. By the time of his marriage, William was able to arrange the appointments of his supporters as bishops and his consolidation of power allowed him to expand his horizons, and by 1062 William was able to secure control of the neighbouring county of Maine. In the 1050s and early 1060s William became a contender for the throne of England, then held by the childless Edward the Confessor, his first cousin once removed. There were other claimants, including the powerful English earl Harold Godwinson. William argued that Edward had previously promised the throne to him, William built a large fleet and invaded England in September 1066, decisively defeating and killing Harold at the Battle of Hastings on 14 October 1066. After further military efforts William was crowned king on Christmas Day 1066 and he made arrangements for the governance of England in early 1067 before returning to Normandy. Several unsuccessful rebellions followed, but by 1075 Williams hold on England was mostly secure, Williams final years were marked by difficulties in his continental domains, troubles with his eldest son, and threatened invasions of England by the Danes. In 1086 William ordered the compilation of the Domesday Book, a listing all the landholders in England along with their holdings. William died in September 1087 while leading a campaign in northern France and his reign in England was marked by the construction of castles, the settling of a new Norman nobility on the land, and change in the composition of the English clergy. He did not try to integrate his various domains into one empire, Williams lands were divided after his death, Normandy went to his eldest son, Robert Curthose, and his second surviving son, William Rufus, received England. Norsemen first began raiding in what became Normandy in the late 8th century, permanent Scandinavian settlement occurred before 911, when Rollo, one of the Viking leaders, and King Charles the Simple of France reached an agreement surrendering the county of Rouen to Rollo. The lands around Rouen became the core of the duchy of Normandy. Normandy may have used as a base when Scandinavian attacks on England were renewed at the end of the 10th century. In an effort to improve matters, King Æthelred the Unready took Emma of Normandy, sister of Duke Richard II, as his second wife in 1002

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

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

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
