Assyrian Calendar
The Assyrian calendar ( ) is a solar calendar used by modern Assyrian people. History Historically and also in some sources in the modern day, Assyrians dated their calendar according to the Seleucid era ( , literally "of the Greeks"), beginning on the first day of in 312 BC. The modern Assyrian calendar, however, uses a different reckoning: 4750 BC was set as its first year in the 1950s, based on a series of articles published in the Assyrian nationalist magazine ''Gilgamesh''; the first came in 1952 and written by Nimrod Simono and dealt with the Akitu festival, then an article by Jean Alkhas in 1955 (April, issue 34) fixed the year 4750 BC as the starting point. Alkhas referenced his information to a French archaeologist, whom he did not name, as stating that a cuneiform tablet dating to 4750 BC mentioned the year of the calming of the great flood and beginning of life. New year The year begins with the first sight of Spring. In the Julian calendar, the vernal equino ...

Solar Calendar
A solar calendar is a calendar whose dates indicates the season or almost equivalently the apparent position of the Sun relative to the stars. The Gregorian calendar, widely accepted as a standard in the world, is an example of a solar calendar. The main other types of calendar are lunar calendar and lunisolar calendar, whose months correspond to cycles of Moon phases. The months of the Gregorian calendar do not correspond to cycles of the Moon phase. The Egyptians appear to have been the first to develop a solar calendar, using as a fixed point the annual sunrise reappearance of the Dog Star— Sirius, or Sothis—in the eastern sky, which coincided with the annual flooding of the Nile River. They constructed a calendar of 365 days, consisting of 12 months of 30 days each, with 5 days added at the year’s end. The Egyptians’ failure to account for the extra fraction of a day, however, caused their calendar to drift gradually into error. Examples The oldest solar calendar ...

Julian Calendar
The Julian calendar is a solar calendar of 365 days in every year with an additional leap day every fourth year (without exception). The Julian calendar is still used as a religious calendar in parts of the Eastern Orthodox Church and in parts of Oriental Orthodox Churches, Oriental Orthodoxy as well as by the Amazigh, Amazigh people (also known as the Berbers). The Julian calendar was proposed in 46 BC by (and takes its name from) Julius Caesar, as a reform of the earlier Roman calendar, which was largely a lunisolar calendar, lunisolar one. It took effect on , by his edict. Caesar's calendar became the predominant calendar in the Roman Empire and subsequently most of the Western world for more than 1,600 years, until 1582 when Pope Gregory XIII promulgated a revised calendar. Ancient Romans typically designated years by the names of ruling consuls; the ''Anno Domini'' system of numbering years was not devised until 525, and became widespread in Europe in the eighth cent ...

Solar Hijri Calendar
The Solar Hijri calendar is the official calendar of Iran. It is a solar calendar, based on the Earth's orbit around the Sun. Each year begins on the day of the March equinox and has years of 365 or 366 days. It is sometimes also called the Shamsi calendar, Khorshidi calendar or Persian calendar. It is abbreviated as SH, HS, AP, or, sometimes as AHSh, while the lunar Hijri calendar (commonly known in the West as the 'Islamic calendar') is usually abbreviated as AH. The epoch (very first day) of the Solar Hijri calendar was the day of the spring equinox, March 19, 622 CE. The calendar is a "Hijri calendar" because that was the year that Mohammed is believed to have left from Mecca to Medina, which event is referred to as the Hijrah. Since the calendar uses astronomical observations and calculations for determining the vernal equinox, it theoretically has no intrinsic error in matching the vernal equinox year. According to Iranian studies, it is older than the lunar Hijri ...

Persian Calendar
The Iranian calendars or Iranian chronologies (, ) are a succession of calendars created and used for over two millennia in Iran, also known as Persia. One of the longest chronological records in human history, the Iranian calendar has been modified many times for administrative purposes. The most influential person in laying the frameworks for the calendar and its precision was the 11th century Persian polymath, Omar Khayyam. The modern Iranian calendar is the Solar Hijri calendar, currently the official civil calendar in Iran. Nowruz, the Iranian New Year, begins at the midnight nearest to the instant of the northern spring equinox, as determined by astronomic calculations for the meridian of Tehran (52.5°E). Thus the calendar is observation-based, unlike the Gregorian calendar, which is rule-based. This equinox occurs on or about 20 March of the Gregorian calendar. The time zone of Iran is Iran Standard Time, UTC+03:30. Ancient calendars The earliest evidence of Ir ...

Mandaean Calendar
The Mandaean calendar is a 365-day solar calendar used by the Mandaean people.Drower, Ethel Stefana. ''The Mandaeans of Iraq and Iran''. Oxford At The Clarendon Press, 1937. It consists of twelve 30-day months, with five extra days at the end of Šumbulta (the 8th month). The Parwanaya (or Panja) festival takes place during those five days. There is no leap year therefore every four years all Mandaean dates (like beginnings of the months or festivals) move one day back with respect to the Gregorian calendar. Months Each month (''iahra'' or ''yahra'') is named after a constellation (''manzalta''). The Mandaic names of the twelve constellations of the Zodiac are derived from common Aramaic roots. As with the seven planets, the constellations, frequently known as the ''trisar'' (, "The Twelve") or ''trisar malwašia'' ("Twelve Constellations") in Mandaic texts, are generally not viewed favorably since they constitute part of the entourage of Ruha, the Queen of the World of Darkn ...

Islamic Calendar
The Hijri calendar (), also known in English as the Islamic calendar, is a lunar calendar consisting of 12 lunar months in a year of 354 or 355 days. It is used to determine the proper days of Islamic holidays and rituals, such as the Ramadan, annual fasting and the annual season for the Hajj, great pilgrimage. In almost all countries where the predominant religion is Islam, the civil calendar is the Gregorian calendar, with Assyrian calendar, Syriac month-names used in the Arabic names of calendar months#Levant and Mesopotamia, Levant and Mesopotamia (Iraq, Syria, Jordan, Lebanon and Palestine), but the religious calendar is the Hijri one.

Babylonian Calendar
The Babylonian calendar was a lunisolar calendar used in Mesopotamia from around the 2nd millennium BC until the Seleucid Era ( 294 BC), and it was specifically used in Babylon from the Old Babylonian Period ( 1780s BC) until the Seleucid Era. In the Seleucid Era it was reformed as "Greek time", Anno Graecorum was introduced and used in the Middle East and Egypt until the middle of the first millennium when the First Council of Nicaea AD 325 defined the Church year based on the Roman early Julian calendar. As Anno Graecorum formed the basis for time references in the Bible and spread westward, it rather increased the Babylonian calendars importance. The Babylonian calendar is also partly reflected in calendars in South and East Asia and the Islamic calendar as well as Iranian calendars. The Julian calendar inherited the definitions of the 12 month system, week, hour etc. from the Babylonian calendar and the current Jewish calendar can be seen as a slightly modified Baby ...

Hebrew Calendar
The Hebrew calendar (), also called the Jewish calendar, is a lunisolar calendar used today for Jewish religious observance and as an official calendar of Israel. It determines the dates of Jewish holidays and other rituals, such as '' yahrzeits'' and the schedule of public Torah readings. In Israel, it is used for religious purposes, provides a time frame for agriculture, and is an official calendar for civil holidays alongside the Gregorian calendar. Like other lunisolar calendars, the Hebrew calendar consists of months of 29 or 30 days which begin and end at approximately the time of the new moon. As 12 such months comprise a total of just 354 days, an extra lunar month is added every 2 or 3 years so that the long-term average year length closely approximates the actual length of the solar year. Originally, the beginning of each month was determined based on physical observation of a new moon, while the decision of whether to add the leap month was based on observation ...

Syriac Language
The Syriac language ( ; ), also known natively in its spoken form in early Syriac literature as Edessan (), the Mesopotamian language () and Aramaic (), is an Aramaic#Eastern Middle Aramaic, Eastern Middle Aramaic dialect.

Gregorian Calendar
The Gregorian calendar is the calendar used in most parts of the world. It went into effect in October 1582 following the papal bull issued by Pope Gregory XIII, which introduced it as a modification of, and replacement for, the Julian calendar. The principal change was to space leap years slightly differently to make the average calendar year 365.2425 days long rather than the Julian calendar's 365.25 days, thus more closely approximating the 365.2422-day tropical year, "tropical" or "solar" year that is determined by the Earth's revolution around the Sun. The rule for leap years is that every year divisible by four is a leap year, except for years that are divisible by 100, except in turn for years also divisible by 400. For example 1800 and 1900 were not leap years, but 2000 was. There were two reasons to establish the Gregorian calendar. First, the Julian calendar was based on the estimate that the average solar year is exactly 365.25 days long, an overestimate of a li ...

Spring (season)
Spring, also known as springtime, is one of the four temperate seasons, succeeding winter and preceding summer. There are various technical definitions of spring, but local usage of the term varies according to local climate, cultures and customs. When it is spring in the Northern Hemisphere, it is autumn in the Southern Hemisphere and vice versa. At the spring equinox, also called the vernal equinox, Daytime (astronomy), days and nights are approximately twelve hours long, with daytime length increasing and nighttime length decreasing as the season progresses until the summer solstice. The spring equinox is in March in the Northern Hemisphere and in September in the Southern Hemisphere, while the summer solstice is in June in the Northern Hemisphere and in December in the Southern Hemisphere. Spring and "springtime" refer to the season, and also to ideas of rebirth, rejuvenation, renewal, resurrection and regrowth. Subtropical and tropical areas have climates better described ...
