Coptic Calendar
The Coptic calendar, also called the Alexandrian calendar, is a liturgical calendar used by the farming populace in Egypt and used by the Coptic Orthodox and Coptic Catholic churches. It was used for fiscal purposes in Egypt until the adoption of the Gregorian calendar on 11 September 1875 (1st Thout 1592 AM). 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 unsynchronised with the original i ...

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 ...

Ethiopian Calendar
The Ethiopian calendar (; ; ), or Geʽez calendar (Geʽez: ; Tigrinya: , ) is the official state civil calendar of Ethiopia and serves as an unofficial customary cultural calendar in Eritrea, and among Ethiopians and Eritreans in the diaspora. It is also an ecclesiastical calendar for Ethiopian Christians and Eritrean Christians belonging to the Orthodox Tewahedo Churches ( Ethiopian Orthodox Tewahedo Church and Eritrean Orthodox Tewahedo Church), Eastern Catholic Churches ( Eritrean Catholic Church and Ethiopian Catholic Church), and Protestant Christian P'ent'ay (Ethiopian-Eritrean Evangelical) Churches. The Ethiopian calendar is a solar calendar that has much in common with the Coptic calendar of the Coptic Orthodox Church of Alexandria and Coptic Catholic Church, but like the Julian calendar, it adds a leap day every four years without exception, and begins the year on 11 or 12th of September in the Gregorian calendar (from 1900 to 2099).

Chronography Of 354
The Chronograph of 354 is a compilation of chronological and calendrical texts produced in 354 AD for a wealthy Roman Christian named Valentinus by the calligrapher and illustrator Furius Dionysius Filocalus. The original illustrated manuscript is lost, but several copies have survived. It is the earliest known codex to have had full page illustrations. The work is also called the Chronography or Calendar of 354, and the name Calendar of Filocalus or Filocalian Calendar is sometimes used to describe the whole collection, and sometimes just the sixth part, which is the Calendar itself. Other versions of the names ("Philocalus", "Philocalian", "Codex-Calendar of 354", etc.) are occasionally used. The text and illustrations are available online. It has had a variety of other names over the years; the historian Theodor Mommsen titled it "Chronica urbis Romae". Amongst other historically significant information, the work contains the earliest reference to the celebration of Christ ...

Hippolytus (writer)
Hippolytus of Rome ( , ; Romanized: , – ) was a Bishop of Rome and one of the most important second–third centuries Christian theologians, whose provenance, identity and corpus remain elusive to scholars and historians. Suggested communities include Rome, Palestine, Egypt, Anatolia and other regions of the Middle East. The best historians of literature in the ancient church, including Eusebius and Jerome, openly confess they cannot name where Hippolytus the biblical commentator and theologian served in leadership. They had read his works but did not possess evidence of his community. Photios I of Constantinople describes him in his '' Bibliotheca'' (cod. 121) as a disciple of Irenaeus, who was said to be a disciple of Polycarp, and from the context of this passage it is supposed that he suggested that Hippolytus so styled himself. This assertion is doubtful. One older theory asserts he came into conflict with the popes of his time and seems to have headed a schismatic group a ...

Metonic Cycle
The Metonic cycle or enneadecaeteris (from , from ἐννεακαίδεκα, "nineteen") is a period of almost exactly 19 years after which the lunar phases recur at the same time of the year. The recurrence is not perfect, and by precise observation the Metonic cycle defined as 235 synodic months is just 2 hours, 4 minutes and 58 seconds longer than 19 tropical years. Meton of Athens, in the 5th century BC, judged the cycle to be a whole number of days, 6,940. Using these whole numbers facilitates the construction of a lunisolar calendar. A tropical year (about 365.24 days) is longer than 12 lunar months (about 354.36 days) and shorter than 13 of them (about 383.90 days). In a Metonic calendar (a type of lunisolar calendar), there are twelve years of 12 lunar months and seven years of 13 lunar months. Application in traditional calendars In the Babylonian and Hebrew lunisolar calendars, the years 3, 6, 8, 11, 14, 17, and 19 are the long (13-month) years of the Metonic c ...

Easter
Easter, also called Pascha ( Aramaic: פַּסְחָא , ''paskha''; Greek: πάσχα, ''páskha'') or Resurrection Sunday, is a Christian festival and cultural holiday commemorating the resurrection of Jesus from the dead, described in the New Testament as having occurred on the third day of his burial following his crucifixion by the Romans at Calvary . It is the culmination of the Passion of Jesus, preceded by Lent (or Great Lent), a 40-day period of fasting, prayer, and penance. Easter-observing Christians commonly refer to the last week of Lent, before Easter, as Holy Week, which in Western Christianity begins on Palm Sunday (marking the entrance of Jesus in Jerusalem), includes Spy Wednesday (on which the betrayal of Jesus is mourned), and contains the days of the Easter Triduum including Maundy Thursday, commemorating the Maundy and Last Supper, as well as Good Friday, commemorating the crucifixion and death of Jesus. In Eastern Christianity, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anno Mundi
(from Latin 'in the year of the world'; ), abbreviated as AM or A.M., or Year After Creation, is a calendar era based on biblical accounts of the creation of the world and subsequent history. Two such calendar eras of notable use are: * Since the Middle Ages, the Hebrew calendar has been based on rabbinic calculations of the year of creation from the Hebrew Masoretic Text of the Bible. This calendar is used within Jewish communities for religious purposes and is one of two official calendars in Israel. In the Hebrew calendar, the day begins at sunset. The calendar's epoch, corresponding to the calculated date of the world's creation, is equivalent to sunset on the Julian proleptic calendar date 6 October 3761 BCE. The new year begins at Rosh Hashanah, in Tishrei. 5785 (meaning the 5,785th year since the creation of the world) began at sunset on October 3, 2024, according to the Gregorian calendar. *The Creation Era of Constantinople was observed by Christian communities ...

Anno Martyrum
The Era of the Martyrs (), also known as the ''Diocletian era'' (), is a method of numbering years based on the reign of Roman Emperor Diocletian who instigated the last major persecution against Christians in the Empire. It was used by the Church of Alexandria beginning in the 4th century AD and it has been used by the Coptic Orthodox Church of Alexandria from the 5th century until the present. This era was used to number the year in Easter tables produced by the Church of Alexandria. Diocletian began his reign on 20 November 284 AD, and the reference epoch (day one of the Diocletian era) was assigned to be the first day of that Alexandrian year, 1 Thoth, the Egyptian New Year, or 29 August 284 AD. Alternatives among early Christians The ''anno Diocletiani'' era was not the only one used by early Christians. Western Christians were aware of it but did not use it. Most Roman Christians, like the pagan Romans before them, designated their years by naming the two consuls wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
