The Ethiopian calendar, the official calendar of Ethiopia: twelve
thirty-day months and a thirteenth epagomenal month, Pagumen, of five
days (six in a leap year), named in Amharic from መስከረም through ጳጉሜ, over
a seven-day week. It runs some seven to eight years behind the Gregorian
calendar, shares the Coptic structure but counts from a later era, and
is a national and liturgical calendar, not an individual's invention.
A year is a leap year when it is congruent to three modulo four -- the
year before a Julian leap year -- so the epagomenal month then runs six
days and the calendar stays in step with the Julian; a common year is
365 days and a leap year 366. The epoch is 29 August AD 8 on the Julian
timeline (Julian Day 1723856).
Its calendar type is
CalendarTypes.ETHIOPIAN, and
it is paired with UTCTimeDefinition.- See Also:
