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 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 ...

September (Roman Month)
September (from Latin ''septem'', "seven") or ''mensis September'' was originally the seventh of ten months on the ancient Roman calendar that began with March (''Martius (month), mensis Martius'', "Mars (mythology), Mars' month"). It had 29 days. After the reforms that resulted in a 12-month year, September became the ninth month, but retained its name. September followed what was originally Sextilis, the "sixth" month, renamed ''Augustus'' in honor of the first Roman emperor, and preceded October (Roman month), October, the "eighth" month that like September retained its numerical name contrary to its position on the calendar. A day was added to September in the mid-40s BC as part of the Julian calendar, Julian calendar reform. September has none of the archaic Roman festivals, festivals that are marked in large letters for other months on List of ancient Roman fasti, extant Roman ''fasti''. Instead, about half the month is devoted to the ''Ludi Romani'', "Roman Games", which dev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sextilis
Sextilis () or ''mensis Sextilis'' was the Latin name for what was originally the sixth month in the Roman calendar The Roman calendar was the calendar used by the Roman Kingdom and Roman Republic. Although the term is primarily used for Rome's pre-Julian calendars, it is often used inclusively of the Julian calendar established by Julius Caesar in 46&nbs ..., when March ('' Martius'', " Mars' month") was the first of ten months in the year. After the calendar reform that produced a twelve-month year, Sextilis became the eighth month, but retained its name. It was renamed ''Augustus'' ( August) in 8 BC in honor of the first Roman emperor, Augustus. Sextilis followed Quinctilis, which was renamed ''Julius'' (July) after Julius Caesar, and preceded September (Roman month), September (from ''septem'', "seven"), which was originally the seventh month. The month ''Augustus'' ''Quintilis, Julius'' (July) was renamed from ''Quintilis'' ("fifth" month) in honor of Julius Ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quintilis
In the ancient Roman calendar, Quintilis or Quinctilis was the month following Junius (June) and preceding Sextilis (August). ''Quintilis'' is Latin for "fifth": it was the fifth month (''quintilis mensis'') in the earliest calendar attributed to Romulus, which began with Martius (" Mars' month," March) and had 10 months. After the calendar reform that produced a 12-month year, Quintilis became the seventh month, but retained its name. In 45 BC, Julius Caesar instituted a new calendar (the Julian calendar) that corrected astronomical discrepancies in the old. After his death in 44 BC, the month of Quintilis, his birth month, was renamed ''Julius'' in his honor, hence July."Los Cielos de Agosto" (Spanish: "The Skies of August"), Jorge R. Ianiszewski, ''Circulo Astronomico'', 2006, webpageCirA-Agosto Quintilis was under the guardianship ''( tutela)'' of the Romans' supreme deity Jupiter, with sacrifices made particularly to Neptune and Apollo.

Iunius (month)
''Mensis Iunius'' or ''Iunius'', also ''Junius'' (June), was the sixth month of the Roman calendar of the classical period, following ''Maius'' (May). In the oldest calendar attributed by the Romans to Romulus, ''Iunius'' had been the fourth month in a ten-month year that began with March ''( Martius,'' "Mars' month"). The month following June was thus called '' Quinctilis'' or ''Quintilis'', the "fifth" month. ''Iunius'' had 29 days until a day was added during the Julian reform of the calendar in the mid-40s BC. The month that followed ''Iunius'' was renamed ''Iulius'' (July) in honour of Julius Caesar. Name of the month In his poem on the Roman calendar, Ovid has three goddesses present three different derivations of the name ''Iunius''. Juno asserts that the month is named for her. Juventas ("Youth") pairs ''Iunius'' with ''Maius'': the former, she says, comes from ''junior'', "a younger person", in contrast to ''maiores'' or the "elders" for whom May was named. Juno's own ...

Maius
''Maius'' or ''mensis Maius'' (May) was the fifth month of the ancient Roman calendar in the classical period, following '' Aprilis'' (April) and preceding '' Iunius'' (June). On the oldest Roman calendar that had begun with March, it was the third of ten months in the year. May had 31 days. The Romans considered May an infelicitous month. Although it began with one of the most notoriously licentious holidays of the Roman calendar, the Games of Flora ''( Ludi Florae)'', the middle of the month was devoted to propitiating the '' lemures'', the restless shades of the dead. Dates The Romans did not number days of a month sequentially from the 1st through the last day. Instead, they counted back from the three fixed points of the month: the Nones (5th or 7th, depending on the length of the month), the Ides (13th or 15th), and the Kalends (1st) of the following month. Thus the last day of May was the ''pridie Kalendas Iunias,'' "day before the Kalends of June". Roman counting was in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aprilis
''Aprilis'' or ''mensis Aprilis'' (April) was the fourth month of the ancient Roman calendar in the classical period, following '' Martius'' (March) and preceding ''Maius'' (May). On the oldest Roman calendar that had begun with March, ''Aprilis'' had been the second of ten months in the year. April had 29 days on calendars of the Roman Republic, with a day added to the month during the reform in the mid-40s BC that produced the Julian calendar. April was marked by a series of festivals devoted to aspects of rural life, since it was a busy month for farmers. As Rome became more urbanized, the significance of some ceremonies expanded, notably the Parilia, an archaic pastoral festival celebrated as the "birthday" ''( dies natalis)'' or founding day of Rome. The month was generally preoccupied with deities who were female or ambiguous in gender, opening with the Feast of Venus on the Kalends. Name of the month The Romans thought that the name ''Aprilis'' derived from ''aperio, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Martius (month)
''Martius'' or ''mensis Martius'' ("March") was the first month of the ancient Roman year until possibly as late as 153 BC. After that time, it was the third month, following ''Februarius'' (February) and preceding '' Aprilis'' ( April). ''Martius'' was one of the few Roman months named for a deity, Mars, who was regarded as an ancestor of the Roman people through his sons Romulus and Remus. March marked a return to the active life of farming, military campaigning, and sailing. It was densely packed with religious observances dating from the earliest period of Roman history. Because of its original position as the first month, a number of festivals originally associated with the new year occurred in March. In the Imperial period, March was also a time for public celebration of syncretic or international deities whose '' cultus'' was spread throughout the empire, including Isis and Cybele. In the agricultural year The '' menologia rustica'' told farmers to expect 12 hours ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intercalaris
Mercedonius (Latin for "Work Month"),. also known as Mercedinus, Interkalaris or Intercalaris (), was the intercalary month of the Roman calendar. The resulting leap year was either 377 or 378 days long. It theoretically occurred every two (or occasionally three) years, but was sometimes avoided or employed by the Roman pontiffs for political reasons regardless of the state of the solar year. Mercedonius was eliminated by Julius Caesar when he introduced the Julian calendar in 45 BC. History This month, instituted according to Roman tradition by Numa Pompilius, was supposed to be inserted every two or three years to align the conventional 355-day Roman year with the solar year. The decision of whether to insert the intercalary month was made by the pontifex maximus, supposedly based on observations to ensure the best possible correspondence with the seasons. However, the pontifex maximus would normally be an active politician, and the decision would often be manipulated to allo ...

Februarius
''Februarius'', fully ''Mensis Februarius'' ("month of Februa"), was the shortest month of the Roman calendar from which the Julian calendar, Julian and Gregorian calendar, Gregorian month of February derived. It was eventually placed second in order, preceded by ''Ianuarius'' ("month of Janus", January) and followed by ''Martius (month), Martius'' ("month of Mars (mythology), Mars", March (month), March). In the oldest Roman calendar, which the Romans believed to have been instituted by their legendary founder Romulus, March was the first month, and the calendar year had only ten months in all. ''Ianuarius'' and ''Februarius'' were supposed to have been added by Numa Pompilius, the second king of Rome, originally at the end of the year. It is unclear when the Romans reset the course of the year so that January and February came first. ''Februarius'' was the only month in the pre-Julian calendar to have an even number of days, numbering 28. This was mathematically necessary to pe ...
