Ethiopian calendar converter
The Ethiopian calendar (Amete Mihret, “Year of Mercy”), also called the Ge’ez calendar, runs about 7 to 8 years behind the Gregorian calendar and is still in everyday use in Ethiopia and Eritrea. Its distinctive feature is a 13th month. This tool converts any date between the Gregorian and Ethiopian systems in both directions, including dates that fall in the short month Pagume.
Why the Ethiopian calendar matters in practice
Business contracts, government filings, bank statements, and official letters in Ethiopia routinely carry Ethiopian calendar dates. If you are working with Ethiopian partners, auditing Ethiopian company records, or booking a flight to Addis Ababa around a holiday such as Enkutatash (New Year) or Timkat (Epiphany), you will need to translate dates in both directions. The calendar also differs from the Gregorian in one more subtle way: the Ethiopian day begins at 6:00 AM, meaning Ethiopian “1 o’clock” in the morning corresponds to 7:00 AM in the Gregorian reckoning — a source of meeting-time confusion.
How it works
The Ethiopian year has 12 months of exactly 30 days plus Pagume, a 13th month of 5 days (6 in a leap year). A year is a leap year when year mod 4 == 3. Rather than juggling these rules directly, the converter pivots through the Julian Day Number — a continuous count of days used in astronomy — converting your input to a JDN and then out to the target calendar. This makes conversions exact and guarantees a value round-trips back to itself. The weekday is derived from the same JDN.

| Pagume length | 5 days, 6 in leap years |
| Leap rule | year mod 4 == 3 |

Worked conversion examples
- Ethiopian → Gregorian: 1 Meskerem 2018 → 11 September 2025
- Gregorian → Ethiopian: 7 January 2026 → 29 Tahsas 2018 (Orthodox Christmas, Genna)
- Gregorian → Ethiopian: 19 January 2026 → 11 Tir 2018 (Timkat, Ethiopian Epiphany)
- Pagume date: 1 Pagume 2017 → 7 September 2025 (the final days before New Year)
When converting a year, remember the offset depends on whether you are before or after the Ethiopian New Year in the Gregorian calendar. Going from Ethiopian to Gregorian: a date in the months Meskerem through Nehase (September to August) sits between 7 and 8 years ahead of its Ethiopian counterpart.
