Convert Hijri and Gregorian dates

The Hijri converter turns a civil Gregorian date into the Umm al-Qura Hijri date, and the other way around. Umm al-Qura is the tabulated civil calendar used in Saudi Arabia. This page reads it through the browser’s internationalization API, calendar islamic-umalqura, which is the data set current browsers ship. It does not look up a moon-sighting announcement, and it does not ask a server what day a local committee declared.

You pick a direction, enter a day, a month, and a year, and the page shows both forms: the Gregorian date with its English weekday, and the Hijri date with the Arabic month name and the English transliteration. Hijri months in the result use the names Muharram through Dhu al-Hijjah, with the Arabic beside them: محرم through ذو الحجة. The Today button fills the civil date on your device and converts that day.

A Hijri month has 29 or 30 days. The length comes from the same tables. If you ask for day 30 of a 29-day month, the page says how long that month is instead of inventing a date. Day 31 is never a Hijri day. A Gregorian date that is not a real day, such as 31 February, is rejected the same way.

The tables in current browsers cover 14 March 1937 through 16 November 2077. Dates outside that window are refused. A guessed conversion for the year 1800 would look confident and be wrong, so the page would rather show an error.

Today is the calendar date on the device you are using, not UTC “today” if you are in a time zone where those differ near midnight. The conversion of that civil day is done at noon UTC internally, so a daylight-saving change cannot push the result to the previous or next day. The weekday you see is the weekday of the Gregorian date.

One date at a time. If a form wants a start and an end, convert each of them. The fields stay on the page until you change them. They are not stored.

Ramadan and the two Eids are sometimes begun when people sight the crescent, and that observed day can be one day away from the civil Umm al-Qura date. Ministries, banks, and visa forms usually want the civil date. A mosque may want the observed one. Use this tool for the civil date printed on a letter or typed into a form. If you are scheduling a fast or a prayer that follows local sighting, confirm the day with the authority you follow. The page is explicit about this because a converter that pretends every country shares one Hijri day causes missed appointments.

Known checks, so you can see which calendar you are on: 11 March 2024 is 1 Ramadan 1445, 10 April 2024 is 1 Shawwal 1445, and 1 March 2025 is 1 Ramadan 1446. If a different site disagrees on those days, it is using another calendar or another data set.

A date is not a file, and it is still your information. The conversion does not leave the browser. QuickConvert does not receive the day you typed. After the page has loaded, you can disconnect and keep converting. Analytics on the public site can see that the tool was opened. Read the Privacy Policy and how to convert Hijri and Gregorian dates.
