The Ethiopian calendar (Amharic የኢትዮጵያ ዘመን አቆጣጠር ye'Ītyōṗṗyā zemen āḳoṭaṭer) is the most important of the calendars used in Ethiopia. It is also used by the Ethiopian Orthodox Church under the name ge'ez calendar. It is based on the Coptic calendar, which in turn is based on the Egyptian calendar, but elements from the Julian calendar have also been included. Like the latter leap year, the calendar has every four years without exception, and the leap year is entered on 29 August or 30 August approx. six months before the anniversary of the shooting on February 29, according to the Gregorian calendar. As the rule for whether the leap year is to be considered coincides with the Gregorian and Ethiopian calendars in the period from 1901 to 2099, the time of the Ethiopian calendar New Year's Day will be fixed on 11 or 12 September, depending on the leap year. (Outside this time interval, it must be corrected that the Gregorian calendar does not count leap years for the whole century except the whole century divisible by 400. This difference means that the time of the Ethiopian New Year's Day falls later and later as the Ethiopian calendar counts more leap days than the Gregorian calendar. ) Like the Coptic calendar, the Ethiopian has twelve months of thirty days, as well as five or six epagomenal days, often called "the thirteenth month." The months begin on the same day as in the Coptic calendar, but have different names, in ge'ez. The anniversary of the leap is entered after August 29, six months before it is entered in the Julian calendar.
