How to use it
- Select the calendar of the date you already know.
- Enter the year, month, and day. Arabic and Western numerals are accepted.
- Convert the date and copy the result if you need to use it elsewhere.
How it works
The converter uses the Umm al-Qura calendar supplied by your browser’s internationalization data. Dates are compared as civil days in UTC so a device’s time zone does not change the result. Supported Hijri years are 1356 through 1500 AH, corresponding to parts of 1937 through 2077 CE.
When to use it
- Read the Gregorian equivalent of a Hijri date printed on an older document.
- Write both calendar dates on a bilingual invitation.
- Compare a date with an official local calendar before using it for an observance or deadline.
Convert 1 March 2025 to Hijri
Select Gregorian to Hijri, then enter year 2025, month 3, and day 1. The result is 1 Ramadan 1446. To reverse it, select Hijri to Gregorian and enter year 1446, month 9, and day 1. Ramadan is the ninth Hijri month.
What happens to your data
Conversion runs in your browser. The entered date is not sent to Marsa.
Frequently asked questions
Why does my local Hijri date differ?
Local moon sightings and official announcements can put the start of a Hijri month on a different civil day. Check the authority relevant to your country or event.
How many days are in a Hijri month?
A month has 29 or 30 days under this convention. The converter rejects a day 30 when the selected month has only 29 days.
