Free Ethiopian Calendar Converter

Worked example

Leave "Conversion direction" on "Gregorian → Ethiopian" and pick 7 January 2025 in "Gregorian date". The result card shows 2017-04-29 in large type, then "29 Tahsas 2017", the Ge'ez form "29 ታኅሳስ 2017" and the weekday, Tuesday. "Copy" puts "2017-04-29 (29 Tahsas 2017)" on the clipboard, and "Copy in Ge'ez script" copies the Ge'ez line. Now press "Ethiopian → Gregorian" and set Day 5, Month "13. Pagume (ጳጉሜ)" and Year 2017. The page says "Pagume has 5 days this year." and shows 2025-09-10, Wednesday. Change Day to 6 and you get "That day doesn't exist in this Ethiopian month."; change Year to 2019 and day 6 gives 2027-09-11.

Which settings to use, and the limits

• Choose the direction first. The two buttons under "Conversion direction" are "Gregorian → Ethiopian" and "Ethiopian → Gregorian". The first uses your browser's date picker. The second has "Day", "Month" and "Year" boxes, where Year is the Ethiopian year. Both start on today's date, taken from your device clock, and the banner at the top, "Today (Ethiopian)", shows today in Latin and Ge'ez letters with a line saying whether that Ethiopian year is a leap year. The weekday is written in the language of the page.
• Use the month list for Pagume. The "Month" menu runs from "1. Meskerem (መስከረም)" to "13. Pagume (ጳጉሜ)". Months 1 to 12 always have 30 days. Pagume has 5 days, or 6 in an Ethiopian leap year, and the line under the boxes tells you which for the year you typed, for example "Pagume has 5 days this year." Leap years come every fourth year: 2015, 2019, 2023 and 2027 have a sixth day, while 2016, 2017 and 2018 do not.
• Do not expect the New Year on the same day every year. 1 Meskerem 2018 falls on 2025-09-11. But 2023-09-11 is still 6 Pagume 2015, because 2015 is a leap year, and 1 Meskerem 2016 starts on 2023-09-12. The Millennium, 1 Meskerem 2000, was 2007-09-12. A rule such as "the New Year is always 11 September" is one day wrong in some years, so type the actual date and read the result.
• Check the supported range and what is converted. "Gregorian → Ethiopian" accepts Gregorian years 100 to 3000, and "Ethiopian → Gregorian" accepts Ethiopian years 1 to 2993. The tool converts calendar dates only: it has no time of day. Gregorian rules are applied to every year, including those before 1582, so an old date can differ from the Julian date written in a historical source. The result is exact day arithmetic, not an estimate.
• Pick the copy button that matches where the date is going. In "Gregorian → Ethiopian" there are two buttons. "Copy" gives the number form with the Latin month, such as "2017-04-29 (29 Tahsas 2017)". "Copy in Ge'ez script" gives only "29 ታኅሳስ 2017", which suits a document in Amharic. In "Ethiopian → Gregorian" the single "Copy" button gives the Gregorian date as year-month-day, such as 2025-09-10. After a click the button reads "Copied!" for a moment.
• Share a conversion as a link. "Share result" makes a link that reopens the same direction and date. The Gregorian link carries the date as g=2025-01-07; the Ethiopian one carries the year, month and day. On a phone it opens the share sheet, and on a computer it copies the link. The date sits after the # in the address, which browsers do not send to the server. The conversion itself happens in your browser.

Common problems and how to fix them

It says "That date is outside the supported range."

The Gregorian date has a year below 100 or above 3000. Choose a date inside that span. If you have an Ethiopian date from a very early year, use "Ethiopian → Gregorian" instead, which starts at Ethiopian year 1. Its answers can fall in Gregorian years below 100, which "Gregorian → Ethiopian" cannot take back.

It says "Enter a valid Gregorian date."

The box holds something that is not a real date written as year-month-day. If your browser shows a plain text box instead of a date picker, type 2025-01-07, not 07/01/2025, and avoid dates that do not exist such as 2025-02-30. If you have filled only part of a date picker, no message and no result appear until the day, month and year are all set.

It says "Enter an Ethiopian year between 1 and 2993."

The Year box is empty, 0, a decimal, or above 2993. Type a whole year from 1 to 2993. The top year, 2993, ends in Gregorian 3001. If you only have a Gregorian year, switch to "Gregorian → Ethiopian" instead of typing it here.

It says "That day doesn't exist in this Ethiopian month."

Check the line under the boxes: it names the month and its length for that year. Months 1 to 12 stop at 30, and Pagume stops at 5 in most years and 6 in leap years. For example, 6 Pagume exists in 2015, 2019, 2023 and 2027 but not in 2017. An empty Day box or a decimal also gives this message. Lower the day, or move to month 1 of the next year.

The Gregorian answer is about eight years later than you expected.

A Gregorian year was typed into the Ethiopian "Year" box. The Ethiopian calendar runs roughly 7 to 8 years behind the Gregorian one, so Ethiopian year 2025 is read as a date in 2032, and 1 Meskerem 2025 comes out as 2032-09-11. Type the Ethiopian year, such as 2017 for dates from September 2024 to September 2025, or use "Gregorian → Ethiopian" to start from the Gregorian date.

How it compares

This converter turns one date into the other with fixed day arithmetic for the Amete Mihret calendar, so it gives the same answer every time. It shows both Latin and Ge'ez month names, the weekday, and whether the year is a leap year. It converts one date at a time and has no month grid, no holiday or fasting list, no date differences and no time of day. A printed calendar shows a whole month at once. For legal or church documents, confirm the date with the office or parish that issues them.
