How the Ethiopian calendar works
The Ethiopian calendar has 13 months. Meskerem through Nehase have 30 days each, and Pagume (ጳጉሜን) has 5 days, or 6 in a leap year. A year is a leap year when its number leaves remainder 3 after dividing by 4, so the extra day is added at the end of year 2015, 2019, 2023 and so on. The year count (Amete Mihret) runs 7 years behind the Gregorian count from the new year, Enkutatash, to 31 December, and 8 years behind for the rest of the Gregorian year.
The rule used
Ethiopian 1 Meskerem 1 is Julian 29 August 8 CE (Julian Day Number 1724221). A date is counted as 365 × (year − 1) + floor(year ÷ 4) + 30 × (month − 1) + (day − 1) days from that epoch and converted through the Julian Day Number to the proleptic Gregorian calendar. Nothing is looked up or estimated, and the code is checked against the browser's own Ethiopic calendar over 300 years.
Worked example
The Ethiopian new year 2019 begins on 11 September 2026 (1 Meskerem 2019), because 2018 was not a leap year. Thirty days into the year, 30 September 2026 is 20 Meskerem 2019. The leap-year Pagume at the end of 2019 has 6 days, so 1 Meskerem 2020 falls on 12 September 2027 instead of the 11th.
Frequently asked questions
How does the Ethiopian calendar differ from the Gregorian calendar?
The Ethiopian calendar has 13 months: twelve of exactly 30 days and a short thirteenth month, Pagume, of 5 days (6 in a leap year). Its year starts on 11 September in the Gregorian calendar (12 September in the year before a Gregorian leap year), and its year number runs about 7 to 8 years behind.
Why is the Ethiopian year 7 or 8 years behind?
The Ethiopian count (Amete Mihret) places the Incarnation about 7 to 8 years later than the Gregorian count. From 1 January to the Ethiopian new year (Enkutatash, around 11 September) the difference is 8 years; from then until 31 December it is 7 years.
When is the Ethiopian leap year?
Every year whose number leaves remainder 3 when divided by 4 (2015, 2019, 2023 and so on) is a leap year, and Pagume then has 6 days. The extra day falls at the end of that Ethiopian year, so the next new year lands on 12 September instead of 11 September.
What are the Amharic month names?
Meskerem (መስከረም), Tikimt (ጥቅምት), Hidar (ኅዳር), Tahsas (ታኅሣሥ), Tir (ጥር), Yekatit (የካቲት), Megabit (መጋቢት), Miazia (ሚያዝያ), Ginbot (ግንቦት), Sene (ሰኔ), Hamle (ሐምሌ), Nehase (ነሐሴ) and Pagume (ጳጉሜን). The English spellings are common transliterations and vary between sources.
How accurate is this converter?
The conversion is exact day arithmetic, and the test suite compares it with the browser's built-in Ethiopic calendar across 300 years. It uses the arithmetic rules of the Amete Mihret calendar. It does not cover the Amete Alem era, and it is not an official or legal document, so confirm certificates with the issuing authority.
