Guide

Convert Ethiopian calendar dates and Gregorian dates

This Ethiopian Date Converter changes Gregorian dates into Ethiopian calendar dates and converts Ethiopian input back into Gregorian dates. It is useful for civil date lookup, document comparison, and checking dates written in the Ethiopian Era.

The Ethiopian calendar has thirteen months: twelve 30-day months plus the short month Pagume. The converter supports that thirteenth month and validates reverse input through ICU so impossible dates are not silently adjusted.

This page uses ICU's ethiopic calendar implementation and focuses on modern Ethiopian calendar conversion. It does not try to model every historical regional calendar variant or local observance rule.

What it handles

Ethiopian calendar conversion coverage

The converter supports both Gregorian to Ethiopian and Ethiopian to Gregorian conversion. Results include the Ethiopian year, month, day, month name, weekday, and the calendar variant label used by the implementation.

The thirteenth month is handled as part of the same validation path as the other months. If an Ethiopian date cannot be represented by ICU with the same year, month, and day, the converter returns an input error.

Gregorian to Ethiopian

Enter a Gregorian date and return the matching Ethiopian calendar date with month label and weekday.

Ethiopian to Gregorian

Enter an Ethiopian date in YYYY-MM-DD format and convert it back into Gregorian form.

Thirteenth-month validation

Pagume dates are accepted only when they are real dates for the entered Ethiopian year.

How to use

Use the Ethiopian conversion modes

Choose Gregorian to Ethiopian when you have a standard Gregorian date. Choose Ethiopian to Gregorian when the source date is already written in Ethiopian calendar year, month, and day numbers.

For Ethiopian input, use YYYY-MM-DD and month numbers 01 through 13. The converter handles the short thirteenth month through the same validation used for all reverse conversions.

1

Choose Gregorian to Ethiopian

Use this direction for a Gregorian date such as 2026-06-30. The result is Ethiopian 2018-10-23.

2

Choose Ethiopian to Gregorian

Use this direction for Ethiopian input such as 2018-10-23. The result is the matching Gregorian date.

3

Enter month 13 carefully

Pagume is short, so not every day number is valid in month 13. Invalid values are rejected after round-trip validation.

FAQ

Ethiopian date conversion notes

Ethiopian date lookup often raises questions about the thirteenth month, era numbering, and the difference between civil conversion and religious observance calendars. These answers define the scope of this page.

Does the converter support Pagume?

Yes. Month 13 is supported, but only real dates in the short month pass validation.

What format should Ethiopian input use?

Use YYYY-MM-DD with an Ethiopian calendar year and month numbers 01 through 13.

Is this a church calendar calculator?

No. This page converts civil calendar dates and does not calculate movable observances or liturgical dates.

Reference

Calendar implementation reference

This converter uses ICU calendar services through PHP Intl. ICU documents the ethiopic calendar identifier and calendar field behavior used for validation and conversion.
