The Ethiopian year consists of 365 days, divided into twelve months of thirty
days each plus one additional month of five days (six in leap years). Ethiopian
New Year's falls on September 11 and ends the following September 10, according
to the Gregorian (Western) calendar. From September 11 to December 31, the Ethiopian
year runs seven years behind the Gregorian year; thereafter, the difference
is eight years. Hence, the Ethiopian year 1983 began on September 11, 1990,
according to the Gregorian calendar, and ended on September 10, 1991. This discrepancy
results from differences between the Ethiopian Orthodox Church and the Roman
Catholic Church as to the date of the creation of the world.
