To indicate the year, Ethiopians and followers of the Eritrean churches today use the Incarnation Era, which dates from the Annunciation or Incarnation of Jesus on 25 March 9 (Julian), as calculated by Annianus of Alexandria c. In Christianity the Annunciation ( grc Ευαγγελισμός της Θεοτόκου, Evangelismós tēs Theotókou in Greek) is the revelation The Incarnation is the belief in Christianity that Jesus Christ is the God of Israel in the flesh Jesus of Nazareth (7–2 BC / BCE —26–36 AD / CE) Events 1199 - Richard I is wounded by a crossbow bolt while fighting France which leads to his death on April 6.

In the past, a number of other eras for numbering years were also widely used in Ethiopia and the Axumite Kingdom:
The most important era – once widely used by the Eastern Churches, and still used by the Coptic Church - was the Era of Martyrs, also known as the Diocletian Era, whose first year began on 29 August 284. An era is a commonly used word for long period of time When used in science for example geology eras denote clearly defined periods of time of arbitrary but well defined Families of churches Eastern Christians have a shared tradition but they became divided ( Schism) during the early centuries of Christianity in disputes about History of the Coptic Orthodox Church of Alexandria Apostolic foundation Egypt is identified in the Bible as the place of refuge that the The anno Diocletiani era or the Diocletian era or the Era of Martyrs is a method of numbering years used by Alexandrian Christians during the Gaius Aurelius Valerius Diocletianus ( ca.

Respectively to the western and Julian New Year's Days about three months later, the difference between the Era of Martyrs and the Anni Domini is 285 (= 15x19) years. This is because in AD 525, Dionysius Exiguus decided to add 15 Metonic cycles to the existing 13 Metonic cycles of the Diocletian Era (15x19 + 13x19 = 532) to obtain an entire 532-year medieval Easter cycle, whose first cycle ended with the year Era of Martyrs 247 (= 13x19) equal to year DXXXI.

It is also because 532 is the product of the Metonic cycle of 19 years and the Solar cycle of 28 years. The solar cycle, or the solar magnetic activity cycle, is the main source of periodic variation of all solar phenomena driving variations in Space weather.
Around AD 400, an Alexandrine monk called Panodoros fixed the Alexandrian Era (Anno Mundi = in the year of the world), the date of creation, on 29 August 5493 BC. la Anno Mundi (Latin "in the year of the World " abbreviated as AM or A Cultures throughout history have believed the world formed or was formed at some time in the past so methods of dating Creation have involved analysing scriptures and some physical During the 6th millennium BC, Agriculture spreads from the Balkans to Italy and Eastern Europe and from Mesopotamia to Egypt. After the 6th century AD, the era was used by Egyptian and Ethiopian chronologists. The twelfth 532-year-cycle of this era began on 29 August 360 AD, and so 4x19 years after the Era of Martyrs.
Bishop Anianos preferred the Annunciation style as New Year's Day, the 25 March (see above). Annianus of Alexandria or Annianos was a monk who flourished in Alexandria during the Bishopric of Theophilus of Alexandria around the beginning Thus he shifted the Panodoros era by about six months, to begin on 25 March 5492 BC.
The four year leap-year cycle is associated with the four Evangelists: the first year after an Ethiopian leap year is named in honour of John, followed by the Matthew-year and then the Mark-year.
