. The Ethiopian calendar has twelve months of thirty days plus five or six epagomenal days, which comprise a thirteenth month. The Ethiopian months begin on the same days as those of the Coptic calendar, but their names are in Ge'ez. A sixth epagomenal day is added every four years, without exception, on 29 August of the Julian calendar, six months before the corresponding Julian leap day. Thus the first day of the Ethiopian calendar year, 1 Mäskäräm, for years between 1900 and 2099 (inclusive), is usually 11 September (Gregorian). It falls on 12 September in years before the Gregorian leap year, however.

, the official language of Ethiopia it is called Enkutatash meaning "Gift of jewels". It occurs on 11 September in the Gregorian Calendar; except for the year preceding a leap year, when it occurs on 12 September. The Ethiopian Calendar Year 1998 ''Amätä Məhrät'' ("Year of Mercy") began on the Gregorian Calendar Year on 11 September 2005. The Ethiopian calendar Years 1992 and 1996, however, began on the Gregorian Dates of '12 September 1999' and '2003' respectively. This date correspondence applies for the Gregorian years 1900 to 2099. The Ethiopian calendar leap year is every four without exception, while Gregorian centurial years are only leap years when exactly divisible by 400; thus a set of corresponding dates will most often apply for a single century. As the Gregorian year 2000 is a leap year, the current correspondence lasts two centuries instead. The start of the Ethiopian calendar year (Feast of El-Nayrouz) falls on 29 or 30 August (in the year just before the Julian leap year). This date corresponds to the Old-Style Julian Calendar; therefore, the start of the year has been transferred forward in the currently used Gregorian Calendar to 11 or 12 September (in the year just before the Gregorian leap year). This deviation between the Julian and the Gregorian Calendar will increase with the passing of the time.


Eras

To indicate the year, followers of the Ethiopian and Eritrean churches today use the ''Incarnation Era'', which dates from the Annunciation or

Anno Mundi according to Panodoros

Around AD 400, an Alexandrine monk called Panodoros fixed the Alexandrian Era (
Anno Mundi (from Latin "in the year of the world"; he, לבריאת העולם, Livryat haOlam, lit=to the creation of the world), abbreviated as AM or A.M., or Year After Creation, is a calendar era based on the biblical accounts of the creation o ...
= in the year of the world), the date of creation, on 29 August 5493 BC. After the 6th century AD, the era was used by Egyptian, Ethiopian, and Eritrean chronologists. The twelfth 532 year-cycle of this era began on 29 August AD 360, and so 4×19 years after the Era of Martyrs.


Anno Mundi according to Anianos

Bishop Anianos preferred the Annunciation style as New Year's Day, 25 March ''(see above)''. Thus he shifted the Panodoros era by about six months, to begin on 25 March 5492 BC. In the Ethiopian calendar this was equivalent to 15 Magabit 5501 B.C. (E.C.). The Anno Mundi era remained in usage until the late 19th century.

though, every 700 years, the month of Pwagme adds a 7th day, which equates to February 30, for further accuracy.


Months

These dates are valid only from March 1900 to February 2100. This is because 1900 and 2100 are not leap years in the Gregorian calendar, while they are still leap years in the Ethiopian calendar, meaning dates before 1900 and after 2100 will be offset.
