Fasli
Adherents of Zoroastrianism use three distinct versions of traditional calendars for liturgical purposes. Those all derive from medieval Iranian calendars and ultimately are based on the Babylonian calendar as used in the Achaemenid empire. ''Qadimi'' ("ancient") is a traditional reckoning introduced in 1006. ''Shahanshahi'' ("imperial") is a calendar reconstructed from the 10th century text ''Denkard''. ''Fasli'' is a term for a 1906 adaptation of the 11th century Jalali calendar following a proposal by Kharshedji Rustomji Cama made in the 1860s. A number of Calendar eras are in use: *A tradition of counting years from the birth of Zoroaster was reported from India in the 19th century. There was a dispute between factions variously preferring an era of 389 BCE, 538 BCE, or 637 BCE. *The "Yazdegerdi era" (also ''Yazdegirdi'' or ''Yazdgerdi'') counts from the accession of the last Sassanid ruler, Yazdegerd III (16 June 632 CE). This convention was proposed by Cama in the 1860s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zoroastrian Festivals
Zoroastrianism has numerous festivals and holy days, all of which are bound to the Zoroastrian calendar. The ''Shahenshahi'' and ''Kadmi'' variants of the calendar do not intercalate leap years and hence the day of the Gregorian calendar year on which these days are celebrated shifts ahead with time. The third variant of the Zoroastrian calendar, known as either ''Fasli'' (in India) or ''Bastani'' (in Iran), intercalates according to Gregorian calendar rules and thus remains synchronous with the seasons. For details on the differences, see Zoroastrian calendar. Seasonal festivals Six irregularly-spaced seasonal festivals, called '' gahanbars'' (meaning "proper season"), are celebrated during the religious year. The six festivals are additionally associated with the six "primordial creations" of Ahura Mazda, otherwise known as the Amesha Spentas, and through them with aspects of creation (the sky, the waters, the earth, plant life, animal life, humankind).

Iranian Calendars
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Astronomical Year Numbering
Astronomical year numbering is based on AD/ CE year numbering, but follows normal decimal integer numbering more strictly. Thus, it has a year 0; the years before that are designated with negative numbers and the years after that are designated with positive numbers. Astronomers use the Julian calendar for years before 1582, including the year 0, and the Gregorian calendar for years after 1582, as exemplified by Jacques Cassini (1740),Jacques Cassini, Tables Astronomiques' (1740), Explication et Usage pp. 5 (PA5), 7 (PA7), Tables pp. 10 (RA1-PA10), 22 (RA1-PA22), 63 (RA1-PA63), 77 (RA1-PA77), 91 (RA1-PA91), 105 (RA1-PA105), 119 (RA1-PA119).

Parthia
Parthia ( ''Parθava''; ''Parθaw''; ''Pahlaw'') is a historical region located in northeastern Greater Iran. It was conquered and subjugated by the empire of the Medes during the 7th century BC, was incorporated into the subsequent Achaemenid Empire under Cyrus the Great in the 6th century BC, and formed part of the Hellenistic Seleucid Empire after the Wars of Alexander the Great, 4th-century BC conquests of Alexander the Great. The region later served as the political and cultural base of the Eastern Iranian languages, Eastern Iranian Parni people and Arsacid dynasty, rulers of the Parthian Empire (247 BC – 224 AD). The Sasanian Empire, the last state of History of Iran, pre-Islamic Iran, also held the region and maintained the Seven Great Houses of Iran, seven Parthian clans as part of their feudal aristocracy. Name The name "Parthia" is a continuation from Latin language, Latin ', from Old Persian ', which was the Parthian language self-designator signifying "of the Pa ...

Seleucid Era
The Seleucid era ("SE") or (literally "year of the Greeks" or "Greek year"), sometimes denoted "AG," was a Calendar era, system of numbering years in use by the Seleucid Empire and other countries among the ancient Hellenistic period, Hellenistic civilizations, and later by the Parthians. It is sometimes referred to as "the dominion of the Seleucidæ," or the Year of Alexander. The era dates from Seleucus I Nicator's reconquest of Babylon in 312/11 BC after his exile in Ptolemaic Kingdom, Ptolemaic Egypt, considered by Seleucus and his court to mark the founding of the Seleucid Empire. According to Jewish tradition, it was during the sixth year of Alexander the Great's reign (lege: possibly Alexander the Great's infant son, Alexander IV of Macedon) that they began to make use of this counting. Versions Two different variations of the Seleucid years existed, one where the year started in spring and another where it starts in autumn: # The natives of the empire used the Babylonian c ...

Regnal Years
A regnal year is a year of the reign of a sovereign, from the Latin meaning kingdom, rule. Regnal years considered the date as an ordinal, not a cardinal number. For example, a monarch could have a first year of rule, a second year of rule, a third year of rule, and so on, but not a zeroth year of rule. Applying this ancient epoch system to modern calculations of time, which include zero, is what led to the debate over when the third millennium began. Regnal years are "finite era names", contrary to "infinite era names" such as Christian era, Jimmu era, ''Juche'' era, and so on. Early use In ancient times, calendars were counted in terms of the number of years of the reign of the current monarch. Reckoning long periods of time required a king list. The oldest such reckoning is preserved in the Sumerian king list. Ancient Egyptian chronology was also dated using regnal years. The Zoroastrian calendar also operated with regnal years following the reform of Ardashir I in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Egyptian Calendar
The ancient Egyptian calendar – a civil calendar – was a solar calendar with a 365-day year. The year consisted of three seasons of 120 days each, plus an Egyptian intercalary month, intercalary month of five epagomenal days treated as outside of the year proper. Each season was divided into four months of 30 days. These twelve months were initially numbered within each season but came to also be known by the names of their principal festivals. Each month was divided into three 10-day periods known as decans or decades. It has been suggested that during the Nineteenth Dynasty of Egypt, Nineteenth Dynasty and the Twentieth Dynasty of Egypt, Twentieth Dynasty the last two days of each decan were usually treated as a kind of weekend for the royal craftsmen, with royal artisans free from work. Because this calendrical year was nearly a quarter of a day shorter than the solar year, the Egyptian calendar lost about one day every four years relative to the Gregorian calendar. It is ...

Northern Vernal Equinox
The March equinox or northward equinox is the equinox on the Earth when the subsolar point appears to leave the Southern Hemisphere and cross the celestial equator, heading northward as seen from Earth. The March equinox is known as the vernal equinox (or spring equinox) in the Northern Hemisphere and as the autumnal equinox (or fall equinox) in the Southern Hemisphere. On the Gregorian calendar at 0° longitude, the northward equinox can occur as early as 19 March (which happened most recently in 1796, and will happen next in 2044), and it can occur as late as 21 March (which happened most recently in 2007, and will happen next in 2102). For a common year the computed time slippage is about 5 hours 49 minutes ''later'' than the previous year, and for a leap year about 18 hours 11 minutes ''earlier'' than the previous year. Balancing the increases of the common years against the losses of the leap years keeps the calendar date of the March equinox from drifting more than one ...

Artaxerxes II
Arses (; 445 – 359/8 BC), known by his regnal name Artaxerxes II ( ; ), was King of Kings of the Achaemenid Empire from 405/4 BC to 358 BC. He was the son and successor of Darius II () and his mother was Parysatis. Soon after his accession, Artaxerxes II faced opposition from his younger brother Cyrus the Younger, who assembled an army composed of troops from his Lydian and Ionians, Ionian satrapies as well as Greek mercenaries in his bid for the throne. The forces of the brothers clashed at Battle of Cunaxa, Cunaxa in 401 BC, which resulted in the defeat and death of Cyrus. Following this, Artaxerxes II had to contend with several other revolts; a revolt by Evagoras I () in Cyprus between 391–380 BC, by the Phoenicians in , and most importantly, the revolts by the western satraps (known as the Great Satraps' Revolt) in the 360s and 350s BC, led by distinguished figures such as Datames, Ariobarzanes of Phrygia, Ariobarzanes, and Autophradates.

Intercalary Month
Intercalation or embolism in timekeeping is the insertion of a leap day, week, or month into some calendar years to make the calendar follow the seasons or moon phases. Lunisolar calendars may require intercalations of days or months. Solar calendars The solar or tropical year does not have a whole number of days (it is about 365.24 days), but a calendar year must have a whole number of days. The most common way to reconcile the two is to vary the number of days in the calendar year. In solar calendars, this is done by adding an extra day ("leap day" or "intercalary day") to a common year of 365 days, about once every four years, creating a leap year that has 366 days ( Julian, Gregorian and Indian national calendars). The Decree of Canopus, issued by the pharaoh Ptolemy III Euergetes of Ancient Egypt in 239 BC, decreed a solar leap day system; an Egyptian leap year was not adopted until 25 BC, when the Roman Emperor Augustus instituted a reformed Alexandrian calendar. ...
