Dating Of Easter
As a moveable feast, the date of Easter is determined in each year through a calculation known as – often simply ''Computus'' – or as paschalion particularly in the Eastern Orthodox Church. Easter is celebrated on the first Sunday after the Paschal full moon (a mathematical approximation of the first astronomical full moon, on or after 21 March itself a fixed approximation of the March equinox). Determining this date in advance requires a correlation between the lunar months and the tropical year, solar year, while also accounting for the month, date, and weekday of the Julian calendar, 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 ce ...

Calendario Pasquale
A calendar is a system of organizing days. This is done by giving names to periods of time, typically days, weeks, months and years. A calendar date, date is the designation of a single and specific day within such a system. A calendar is also a physical record (often paper) of such a system. A calendar can also mean a list of planned events, such as a court calendar, or a partly or fully chronological list of documents, such as a calendar of wills. Periods in a calendar (such as years and months) are usually, though not necessarily, synchronized with the cycle of the solar calendar, sun or the lunar calendar, moon. The most common type of pre-modern calendar was the lunisolar calendar, a lunar calendar that occasionally adds one intercalary month to remain synchronized with the solar year over the long term. Etymology The term ''calendar'' is taken from , the term for the first day of the month in the Roman calendar, related to the verb 'to call out', referring to the " ...

Bede
Bede (; ; 672/326 May 735), also known as Saint Bede, Bede of Jarrow, the Venerable Bede, and Bede the Venerable (), was an English monk, author and scholar. He was one of the most known writers during the Early Middle Ages, and his most famous work, '' Ecclesiastical History of the English People'', gained him the title "The Father of English History". He served at the monastery of St Peter and its companion monastery of St Paul in the Kingdom of Northumbria of the Angles. Born on lands belonging to the twin monastery of Monkwearmouth–Jarrow in present-day Tyne and Wear, England, Bede was sent to Monkwearmouth at the age of seven and later joined Abbot Ceolfrith at Jarrow. Both of them survived a plague that struck in 686 and killed the majority of the population there. While Bede spent most of his life in the monastery, he travelled to several abbeys and monasteries across the British Isles, even visiting the archbishop of York and King Ceolwulf of Northumbria. ...

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 conti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Cyril Of Alexandria
Cyril of Alexandria (; or ⲡⲓ̀ⲁⲅⲓⲟⲥ Ⲕⲓⲣⲓⲗⲗⲟⲥ; 376–444) was the Patriarch of Alexandria from 412 to 444. He was enthroned when the city was at the height of its influence and power within the Roman Empire. Cyril wrote extensively and was a major player in the Christological controversies of the late-4th and 5th centuries. He was a central figure in the Council of Ephesus in 431, which led to the deposition of Nestorius as Patriarch of Constantinople. Cyril is counted among the Church Fathers and also as a Doctor of the Church, and his reputation within the Christian world has resulted in his titles ''Pillar of Faith'' and ''Seal of all the Fathers''. The Nestorian bishops at their synod at the Council of Ephesus declared him a heretic, labelling him as a "monster, born and educated for the destruction of the church". Cyril is well known for his dispute with Nestorius and his supporter, Patriarch John of Antioch, whom Cyril exclude ...

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 ...

Anatolius Of Laodicea
Anatolius of Laodicea (; early 3rd century – July 3, 283"Lives of the Saints," Omer Englebert New York: Barnes & Noble Books, 1994, p. 256.), also known as Anatolius of Alexandria, was a Syro- Egyptian saint and Bishop of Laodicea on the Mediterranean coast of Roman Syria in AD 268. He was not only one of the foremost scholars of his day in the physical sciences, as well as in Aristotelian and Platonic philosophies, but also a renowned computist and teacher of the Neoplatonic philosopher Iamblichus. Anatolius is recognised as a saint by the Roman Catholic Church. His feast day, like Saint Anatolius of Constantinople, is celebrated on 3 July. Life Anatolius was born and raised in Alexandria, Egypt, during the early 3rd century. Prior to becoming one of the great lights of the Church, Anatolius enjoyed considerable prestige at Alexandria while working as a senator. According to Eusebius of Caesarea, he was credited with a rich knowledge of arithmetic, geometry, physics ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Augustalis (bishop)
Augustalis () was the first bishop of Toulon, according to some authorities. He was appointed in 441. He attended the Council of Orange that year, and the Council of Vaison the following. He is associated with the '' civitas'' of Arles ( ancient Arelate) by the '' Martyrologium Hieronymianum'', which honors him on September 7. He is also named by the '' Martyrologium romanum'' on that day, with his location noted as ''in Gallia''. An Augustalis, most likely this man, appears among a group of bishops addressed by Pope Leo I in letters dated 22 August 449 and 5 May 450, the latter of which addresses issues of jurisdiction between Arles and Vienne. ''De ratione Paschae'' :''See also Computus and Epact.'' The bishop, or another churchman named Augustalis in Gaul of the 5th century (possibly the 3rd) was the author of a tract ''De ratione Paschae'', a table or laterculus on calculating the Paschal cycle. He is referenced in the Carthaginian Computus of 455, preserved in an 8th- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Hippolytus Of Rome
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 (Photius), 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 heade ...

Gregorian Reform Of The 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" 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 little under one ...

Oriental Orthodoxy
The Oriental Orthodox Churches are Eastern Christian churches adhering to Miaphysite Christology, with approximately 50 million members worldwide.
