Hijri ↔ Gregorian Date Converter

Because most sites use an arithmetic approximation or the browser's built-in calendar, and both disagree with the published Umm al-Qura calendar on roughly 39% of days before 1420 AH. A decisive example: 1 Muharram 1400 fell on 20 November 1979, while those methods place it on the 19th. This tool uses the published table itself.

It is the official Hijri calendar of Saudi Arabia. Its month lengths are calculated astronomically for Mecca and published in advance, and it is the calendar used in official documents and transactions — which is why it, and not an approximation, is the correct basis for converting dates.

From 1 Muharram 1343 AH (1 August 1924) to 30 Dhu al-Hijjah 1500 AH (16 November 2077), which is the span of the published calendar. Enter a date outside it and you get a clear message saying so, rather than an approximate figure that may be wrong.

Yes, and this is exactly where other converters fail. Dates before 1999 are precisely where approximate methods drift by a full day, while this converter uses the official table across the entire range.
