Concurrent (Easter)
A concurrent was the weekday of 24 March in the Julian calendar counted from , regarding as Sunday. It was used to calculate the Julian Easter during the Middle Ages. It was derived from the weekday of the first day of the Alexandrian calendar during the 4th century, , counting Wednesday as (see Planetary hours#History). Therefore, the following was a Sunday and the following was also a Sunday..

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 ...

Alexandrian Calendar
The Coptic calendar, also called the Alexandrian calendar, is a liturgical calendar used by the Coptic Orthodox Church and also used by the farming populace in Egypt. It was used for fiscal purposes in Egypt until the adoption of the Gregorian calendar on 11 September (6 Nesi) 1875. This calendar is based on the ancient Egyptian calendar. To avoid the calendar creep of the latter (which contained only 365 days each year, year after year, so that the seasons shifted about one day every four years), a reform of the ancient Egyptian calendar was introduced at the time of Ptolemy III (Decree of Canopus, in 238 BC) which consisted of adding an extra day every fourth year. However, this reform was opposed by the Egyptian priests, and the reform was not adopted until 25 BC, when the Roman Emperor Augustus imposed the Decree upon Egypt as its official calendar (although initially, namely between 25 BC and AD 5, it was unsynchronized with the newly introduced Julian calendar which had er ...

Thoth
Thoth (; from grc-koi, Θώθ ''Thṓth'', borrowed from cop, Ⲑⲱⲟⲩⲧ ''Thōout'', Egyptian: ', the reflex of " eis like the Ibis") is an ancient Egyptian deity. In art, he was often depicted as a man with the head of an ibis or a baboon, animals sacred to him. His feminine counterpart was Seshat, and his wife was Ma'at. He was the god of the moon, wisdom, writing, hieroglyphs, science, magic, art, and judgment. His Greek equivalent is Hermes. Thoth's chief temple was located in the city of Hermopolis ( egy, ḫmnw , Egyptological pronunciation: "Khemenu", cop, Ϣⲙⲟⲩⲛ ''Shmun''). Later known as ''el-Ashmunein'' in Egyptian Arabic, the Temple of Thoth was mostly destroyed before the beginning of the Christian era, but its very large pronaos was still standing in 1826. In Hermopolis, Thoth led "the Ogdoad", a pantheon of eight principal deities, and his spouse was Nehmetawy. He also had numerous shrines in other cities. Thoth played many vital and promin ...

Planetary Hours
The planetary hours are an ancient system in which one of the seven classical planets is given rulership over each day and various parts of the day. Developed in Hellenistic astrology, it has possible roots in older Babylonian astrology, and it is the origin of the names of the days of the week as used in English and numerous other languages. The classical planets are Saturn, Jupiter, Mars, Sun, the Sun, Venus, Mercury (planet), Mercury and Moon, the Moon, and they take rulership over the hours in this sequence. The sequence is from slowest- to fastest-moving as the planets appear in the night sky, and so is from furthest to nearest in the planetary spheres model. This order has come to be known as the "Chaldean order". As each day is divided into 24 hours, the first hour of a day is ruled by the planet three places down in the Chaldean order from the planet ruling the first hour of the preceding day; i.e. a day with its first hour ruled by the Sun ("Sunday") is followed by ...

Phamenoth
Paremhat ( cop, Ⲡⲁⲣⲉⲙϩⲁⲧ), also known as Phamenoth ( grc-gre, Φαμενώθ, ''Phamenṓth'') and Baramhat. ( ar, برمهات), is the seventh month of the ancient Egyptian and Coptic calendars. It lies between March 10 and April 8 of the Gregorian calendar. Paremhat is also the third month of the Season of the Emergence, when the Nile floods recede and the crops start to grow throughout the land of Egypt. Name The Coptic name ''Paremhat'' comes from the ancient Egyptian name "Month of Amenhotep I Amenhotep I () ( egy, jmn-ḥtp(w) /jaˌmanuwˈħatpaw/ " Amun is satisfied"; Amarna cuneiform ''a-ma-an-ha-at-pe'' or ''-at-pa''), Amenôthes I, or Amenophis I, (,) from Ancient Greek Ἀμένωφις ,Dodson & Hilton (2004) p.126 additionally ..."

Dionysius Exiguus
Dionysius Exiguus (Latin for "Dionysius the Humble", Greek: Διονύσιος; – ) was a 6th-century Eastern Roman monk born in Scythia Minor. He was a member of a community of Scythian monks concentrated in Tomis (present day Constanța, Romania), the major city of Scythia Minor. Dionysius is best known as the inventor of Anno Domini (AD) dating, which is used to number the years of both the Gregorian calendar and the (Christianised) Julian calendar. Almost all churches adopted his ''computus'' for the dates of Easter. From around the year 500 until his death, Dionysius lived in Rome. He translated 401 Church canons from Greek into Latin, including the Apostolic Canons and the decrees of the First Council of Nicaea, First Council of Constantinople, Council of Chalcedon, and Council of Sardica, and a collection of the decretals of the popes from Siricius to Anastasius II. These '' Collectiones canonum Dionysianae'' had great authority in the West, and they continue to gu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computus
As a moveable feast, the date of Easter is determined in each year through a calculation known as (). Easter is celebrated on the first Sunday after the Paschal full moon, which is the first full moon on or after 21 March (a fixed approximation of the March equinox). Determining this date in advance requires a correlation between the lunar months and the solar year, while also accounting for the month, date, and weekday of the Julian or Gregorian calendar. The complexity of the algorithm arises because of the desire to associate the date of Easter with the date of the Jewish feast of Passover which, Christians believe, is when Jesus was crucified. It was originally feasible for the entire Christian Church to receive the date of Easter each year through an annual announcement by the Pope. By the early third century, however, communications in the Roman Empire had deteriorated to the point that the church put great value in a system that would allow the clergy to determine ...

Epagomenal
The intercalary month or epagomenal days. of the ancient Egyptian, Coptic, and Ethiopian calendars are a period of five days in common years and six days in leap years in addition to those calendars' 12 standard months, sometimes reckoned as their thirteenth month. They originated as a periodic measure to ensure that the heliacal rising of Sirius (star), Sirius would occur in the Mesori, 12th month of the Egyptian lunar calendar but became a regular feature of the civil calendar and its descendants. Coptic and Ethiopian leap days occur in the year preceding Julian calendar, Julian and Gregorian calendar, Gregorian leap years. Names The English names "intercalary month" and "epagomenal days" derive from Latin ' ("proclaimed between") and Greek language, Greek ''epagómenoi'' () or ''epagómenai'' (, "brought in" or "added on"), Latinisation of names, Latinized as '. The period is also sometimes known as the "monthless days". In ancient Egypt, the period was known as the "Five ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bissextile Day
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 multiple ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
