Fasli
Adherents of Zoroastrianism use three distinct versions of traditional calendars for liturgical purposes, all derived from medieval Iranian calendars and ultimately 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'') counts from the accession of the last Sassanid ruler, Yazdegerd III (16 June 632 CE). This convention was proposed by Cama in the 1860s but has since also been u ... [...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 chronology ( fa, گاهشماری ایرانی, ) are a succession of calendars invented or 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 time and again during its history to suit administrative, climatic, and religious purposes. The most influential person in laying the frameworks for the calendar and its precision was the 11th century Persian polymath, hakim Omar Khayyam. The modern Iranian calendar is currently the official civil calendar in Iran and Afghanistan. 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 (52.5°E). It is, therefore, an observation-based calendar, unlike the Gregorian, 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, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gregorian Calendar
The Gregorian calendar is the calendar used in most parts of the world. It was introduced in October 1582 by Pope Gregory XIII as a modification of, and replacement for, the Julian calendar. The principal change was to space leap years differently so as to make the average calendar year 365.2425 days long, more closely approximating the 365.2422-day 'tropical' or 'solar' year that is determined by the Earth's revolution around the Sun. The rule for leap years is: There were two reasons to establish the Gregorian calendar. First, the Julian calendar assumed incorrectly that the average solar year is exactly 365.25 days long, an overestimate of a little under one day per century, and thus has a leap year every four years without exception. The Gregorian reform shortened the average (calendar) year by 0.0075 days to stop the drift of the calendar with respect to the equinoxes.See Wikisource English translation of the (Latin) 1582 papal bull '' Inter gravissimas''.

Avesta
The Avesta () is the primary collection of religious texts of Zoroastrianism, composed in the Avestan language. The Avesta texts fall into several different categories, arranged either by dialect, or by usage. The principal text in the liturgical group is the ''Yasna'', which takes its name from the Yasna ceremony, Zoroastrianism's primary act of worship, and at which the ''Yasna'' text is recited. The most important portion of the ''Yasna'' texts are the five Gathas, consisting of seventeen hymns attributed to Zoroaster himself. These hymns, together with five other short Old Avestan texts that are also part of the ''Yasna'', are in the Old (or 'Gathic') Avestan language. The remainder of the ''Yasna'''s texts are in Younger Avestan, which is not only from a later stage of the language, but also from a different geographic region. Extensions to the Yasna ceremony include the texts of the ''Vendidad'' and the ''Visperad''. The ''Visperad'' extensions consist mainly of addit ...

Hormizd I
Hormizd-Ardashir, better known by his dynastic name of Hormizd I (also spelled Hormozd I or Ohrmazd I; pal, 𐭠𐭥𐭧𐭥𐭬𐭦𐭣), was the third Sasanian King of Kings (''shahanshah'') of Iran, who ruled from May 270 to June 271. He was the third-born son of Shapur I (), under whom he was governor-king of Armenia, and also took part in his father's wars against the Roman Empire. Hormizd I's brief time as ruler of Iran was largely uneventful. He built the city of Hormizd-Ardashir (present-day Ahvaz), which remains a major city today in Iran. He promoted the Zoroastrian priest Kartir to the rank of chief priest (''mowbed'') and gave the Manichaean prophet Mani permission to continue his preaching. It was under Hormizd I that the title of "King of Kings of Iran and non-Iran" became regularized in Sasanian coinage; previously, the royal titulary had generally been "King of Kings of Iran." Hormizd I was succeeded by his eldest brother Bahram I. Etymology The name of Hormizd ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calendar Reform
Calendar reform or calendrical reform is any significant revision of a calendar system. The term sometimes is used instead for a proposal to switch to a different calendar design. Principles The prime objective of a calendar is to unambiguously identify any day in past, present and future by a specific date in order to record or organize social, religious, commercial or administrative events. Recurring periods that contain multiple days, like weeks, months and even years, are secondary, convenient features of a calendar. Most cultures adopt a primary dating system, but different cultures have always needed to align multiple calendars with each other, because they coexisted in the same space (e.g. secular and religious groups with different demands) or had established trading relations. Once specified, a ''calendar design'' cannot be altered without becoming a new design. If a proposed design is sufficiently close to the legacy one, i.e. compatible with it, a ''reform'' of t ...

Parthia
Parthia ( peo, 𐎱𐎼𐎰𐎺 ''Parθava''; xpr, 𐭐𐭓𐭕𐭅 ''Parθaw''; pal, 𐭯𐭫𐭮𐭥𐭡𐭥 ''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 following the 4th-century-BC conquests of Alexander the Great. The region later served as the political and cultural base of the Eastern Iranian Parni people and Arsacid dynasty, rulers of the Parthian Empire (247 BC – 224 AD). The Sasanian Empire, the last state of pre-Islamic Iran, also held the region and maintained the seven Parthian clans as part of their feudal aristocracy. Name The name "Parthia" is a continuation from Latin ', from Old Persian ', which was the Parthian language self-designator signifying "of the Parthians" who were an Iranian ...

Seleucid Era
The Seleucid era ("SE") or (literally "year of the Greeks" or "Greek year"), sometimes denoted "AG," was a system of numbering years in use by the Seleucid Empire and other countries among the ancient Hellenistic civilizations. It is sometimes referred to as "the dominion of the Seleucidæ," or the Year of Alexander. The era dates from Seleucus I Nicator's re-conquest of Babylon in 312/11 BC after his exile in 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. The introduction of the new era is mentioned in one of the Babylonian Chronicles, ''the Chronicle of the Diadochi''. 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 th ...

Regnal Years
A regnal year is a year of the reign of a monarch, sovereign, from the Latin ''regnum'' meaning kingdom, rule. Regnal years considered the date as an ordinal number (linguistics), ordinal, not a cardinal number (linguistics), 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 year zero, zeroth year of rule. Applying this ancient Epoch (reference date), epoch system to modern calculations of time, which include zero, is what led to the Millennium#Debate over millennium celebrations, debate over when the third millennium began. Regnal years are "finite era names", contrary to "infinite era names" such as Anno Domini, Christian era, Japanese imperial year, Jimmu era, North Korean calendar, ''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 times required a king list. The olde ...

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 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 and the 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 therefore sometimes referred to as the ( la, annus vagus), as its months rotated a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 (spring equinox) in the Northern Hemisphere and as the autumnal equinox in the Southern Hemisphere. On the Gregorian calendar, the northward equinox can occur as early as 19 March or as late as 21 March at 0° longitude. 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 day from 20 March each year. The March equinox may be taken to mark the beginning of astronomical spring and the end of astronomical winter in the Northern Hemisphere but ma ...
