  To indicate the year, followers of the Ethiopian and Eritrean churches today use the Incarnation Era, which dates from the Annunciation of the Incarnation of Jesus on 25 March AD 9 (Julian), as calculated by Annianus of Alexandria c. 400; thus, its first civil year began seven months earlier on 29 August AD 8. Meanwhile, Europeans eventually adopted the calculations made by Dionysius Exiguus in AD 525 instead, which placed the Annunciation nine years earlier (Anno Domini#New year) than had Annianus. This causes the Ethiopian year number to be eight years less than the Gregorian year number from January 1 until 10 or 11 September, then seven years less for the remainder of the Gregorian year.
