Intercalaris
Mercedonius (Latin for "Work Month").) before beginning to be treated as nouns in their own right. ' seems to derive from ', meaning "wages"., also known as Mercedinus, Interkalaris or Intercalaris ( la, mensis 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 sea ...

Julian Calendar
The Julian calendar, proposed by Roman consul Julius Caesar in 46 BC, was a reform of the Roman calendar. It took effect on , by edict. It was designed with the aid of Greek mathematicians and astronomers such as Sosigenes of Alexandria. The 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 minor modification to reduce the average length of the year from 365.25 days to 365.2425 days and thus corrected the Julian calendar's drift against the solar year. Worldwide adoption of this revised calendar, which became known as the Gregorian calendar, took place over the subsequent centuries, first in Catholic countries and subsequently in Protestant countries of the Western Christian world. The Julian calendar is still used in parts of the Eastern Orthodox Church and in parts of Oriental Orthodoxy as well as by the Berbers. The Julian calenda ...

Roman Calendar
The Roman calendar was the calendar used by the Roman Kingdom and Roman Republic. The term often includes the Julian calendar established by the reforms of the Roman dictator, dictator Julius Caesar and Roman emperor, emperor Augustus in the late 1stcenturyBC and sometimes includes any system dated by inclusive counting towards months' kalends, nones (calendar), nones, and ides (calendar), ides in the Roman manner. The term usually excludes the Alexandrian calendar of Roman Egypt, which continued the unique months of that land's Egyptian calendar, former calendar; the Byzantine calendar of the Byzantine Empire, later Roman Empire, which usually dated the Roman months in the simple count of the ancient Greek calendars; and the Gregorian calendar, which refined the Julian system to bring it into still closer alignment with the tropical year. Roman dates were counted inclusively forward to the next of three principal days: the first of the month (the kalends), a day shortly befor ...

Leap Year
A leap year (also known as an intercalary year or bissextile year) is a calendar year that contains an additional day (or, in the case of a lunisolar calendar, a month) added to keep the calendar year synchronized with the astronomical year or seasonal year. Because astronomical events and seasons do not repeat in a whole number of days, calendars that have a constant number of days in each year will unavoidably drift over time with respect to the event that the year is supposed to track, such as seasons. By inserting (called '' intercalating'' in technical terminology) an additional day or month into some years, the drift between a civilization's dating system and the physical properties of the Solar System can be corrected. A year that is not a leap year is a common year. For example, in the Gregorian calendar, each leap year has 366 days instead of 365, by extending February to 29 days rather than the common 28. These extra days occur in each year that is an integer multipl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Undecimber
Undecimber or Undecember is a name for a thirteenth month in a calendar that normally has twelve months. Duodecimber or Duodecember is similarly a fourteenth month. Etymology The word ''undecimber'' is based on the Latin word ''undecim'' meaning "eleven". It is formed in analogy with ''December,'' which, though the twelfth month in the Gregorian calendar, derives from ''decem'' meaning "ten". The word ''undecember'' (abbreviated ''Vnde'') is recorded from a Roman inscription according to the Oxford Latin Dictionary, which defines it as "a humorous name given to the month following December". Some recent authors report the names "Undecember" and "Duodecember" for the two intercalary months inserted between November and December upon the adoption of the Julian calendar in 44 BC, including the World Calendar Association and Isaac Asimov. This claim has no contemporary evidence; Cicero refers to the months as ''intercalaris prior'' and ''intercalaris posterior'' in his letters. Histor ...

Latin Language
Latin (, or , ) is a classical language belonging to the Italic languages, Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italy (geographical region), Italian region and subsequently throughout the Roman Empire. Even after the Fall of the Western Roman Empire, fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a fusional language, highly inflected language, with three distinct grammatical gender, genders (masculine, feminine, and neuter), six or seven ...

Adar
Adar ( he, אֲדָר ; from Akkadian ''adaru'') is the sixth month of the civil year and the twelfth month of the religious year on the Hebrew calendar, roughly corresponding to the month of March in the Gregorian calendar. It is a month of 29 days. Names and Leap Years The month's name, like all the others from the Hebrew calendar, was adopted during the Babylonian captivity. In the Babylonian calendar the name was Araḫ Addaru or Adār ('Month of Adar'). In leap years, it is preceded by a 30-day intercalary month named Adar Aleph ( he, אדר א׳, Aleph being the first letter of the Hebrew alphabet), also known as "Adar Rishon" (''First Adar'') or "Adar I", and it is then itself called Adar Bet ( he, אדר ב׳, Bet being the second letter of the Hebrew alphabet, also known as "Adar Sheni" (''Second Adar'' or "Adar II"). Occasionally instead of Adar I and Adar II, "Adar" and "Ve'Adar" are used (Ve means 'and' thus: And-Adar). Adar I and II occur during February–March o ...

Elias Joseph Bickerman
Elias Bickerman (July 7, 1897 O.S. in Russia – August 31, 1981 in Jerusalem), also spelled as Bickermann or Bikerman, was a leading scholar of Greco-Roman history and the Hellenistic world. Biography Bickerman was born in Kishinev, then part of the Russian Empire, to a secular Jewish family. He left Russia during the Bolshevik revolution and the Russian civil war for Germany, where he received education from German classicists and Hellenists. Due to the rise of the Nazi Party to power and his Jewish heritage, he fled to France. He soon had to abandon that country as well after the Battle of France. Since 1942 he lived in the U.S. His research interests extended to Judaism and some aspects of Iranian history. For most of his career, he was Professor of Ancient History at Columbia University, New York. Work Bickerman's scholarship of the Maccabean revolt was highly influential.

Christian Ludwig Ideler
Christian Ludwig Ideler (21 September 1766 – 10 August 1846) was a German people, German chronologist and astronomer. Life He was born in Gross-Brese near Perleberg. His earliest work was the editing in 1794 of an astronomical almanac for the Prussian government. He taught mathematics and mechanics in the school of woods and forests, and also in the military school. In 1821, he became professor at the Humboldt University of Berlin, University of Berlin, and in 1829 became a foreign member of the Institute of France. From 1816 to 1822 he was tutor to the young princes William Frederick and Charles. He died in Berlin on 10 August 1846. This source reports Ideler becoming a member of the French Institute 18 years after becoming a professor in Berlin. Works He devoted his life chiefly to the examination of ancient systems of chronology.

Season
A season is a division of the year based on changes in weather, ecology, and the number of daylight hours in a given region. On Earth, seasons are the result of the axial parallelism of Earth's tilted orbit around the Sun. In temperate and polar regions, the seasons are marked by changes in the intensity of sunlight that reaches the Earth's surface, variations of which may cause animals to undergo hibernation or to migrate, and plants to be dormant. Various cultures define the number and nature of seasons based on regional variations, and as such there are a number of both modern and historical cultures whose number of seasons varies. The Northern Hemisphere experiences most direct sunlight during May, June, and July, as the hemisphere faces the Sun. The same is true of the Southern Hemisphere in November, December, and January. It is Earth's axial tilt that causes the Sun to be higher in the sky during the summer months, which increases the solar flux. However, due to seas ...

Tropical Year
A tropical year or solar year (or tropical period) is the time that the Sun takes to return to the same position in the sky of a celestial body of the Solar System such as the Earth, completing a full cycle of seasons; for example, the time from vernal equinox to vernal equinox, or from summer solstice to summer solstice. It is the type of year used by tropical solar calendars. The solar year is one type of astronomical year and particular orbital period. Another type is the sidereal year (or sidereal orbital period), which is the time it takes Earth to complete one full orbit around the Sun as measured with respect to the fixed stars, resulting in a duration of 20 minutes longer than the tropical year, because of the precession of the equinoxes. Since antiquity, astronomers have progressively refined the definition of the tropical year. The entry for "year, tropical" in the '' Astronomical Almanac Online Glossary'' states: An equivalent, more descriptive, definition is "The ...
