Ethiopia is the only African country whose ancient calendar system has survived for thousands of years. It developed in conversation with older systems — especially Julian and Coptic calendars — yet remains distinctive in daily life, the Church, and national holidays.
The Eastern Orthodox and Ethiopian Orthodox Churches did not adopt the Gregorian calendar for ecclesiastical reckoning. Ethiopia continues to use a Julian-based system with traditional tables (including Bahre Hassab, “the Sea of Thought”) for calculating Easter and many religious feasts.
An Ethiopian year has 365 days, with an extra day every fourth year (366). The year is divided into 13 months: twelve months of 30 days each, plus Pagume (Pagumiene), which has 5 days — or 6 in a leap year. New Year falls in Meskerem (around early September in the Gregorian calendar).
