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.

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
