How to use this calculator
Enter a Gregorian date or numeric Ethiopian year, month and day. Gregorian coverage is 1900-2100.
Conversion uses the browser's ICU Ethiopic calendar. Twelve thirty-day months precede the five- or six-day thirteenth month. This date conversion does not translate Ethiopian clock notation.
A worked example
Gregorian September 11, 2026 corresponds to Ethiopian 2019-01-01, the first day of Meskerem.
Is Ethiopian time-of-day conversion included?
No. Civil calendar dates and local clock notation are separate. This tool converts dates only.
Which calendar and years are supported?
Each result states its calendar, time scale, precision and supported range. Batch converters accept up to 100 nonempty input lines and retain invalid rows. Copy, CSV and print include the calculation rules. Calendar downloads appear when a result contains dated events. Calculations run in your browser; no reminders or jobs are scheduled.
What happens to my dates?
Calculations run on your device. Saving a calculation is optional and keeps it in this browser. A setup link contains the dates and settings you entered; anyone with the link can read them. Use one tab per saved calculator. Clear saved data from Privacy & settings.
