How does the Hijri to Gregorian converter work?
Pick a direction, enter any date, and the converter shows the same day in the other calendar with the weekday and the Arabic month name. It runs entirely in your browser and works in both directions, Hijri to Gregorian and Gregorian to Hijri.
Which Islamic calendars does the converter support?
Three: the Umm al-Qura calendar, the official civil calendar of Saudi Arabia, covered for 1318 to 1499 AH (about 1900 to 2076 CE); the tabular civil calendar, a fixed 30-year arithmetic cycle (the ISO and Unicode islamic-civil rule); and the tabular astronomical variant, the same cycle with an epoch one day earlier.
How accurate is the conversion?
Each result is exact within its own calendar: Umm al-Qura dates come from the official published tables and tabular dates from a fixed arithmetic rule. A civil calculation can still differ by about a day from the actual crescent sighting, so for fasting, Eid, and other observances follow the announcement of your local religious authority.
Why do the calendars sometimes disagree by a day?
They define the start of the month differently. Umm al-Qura follows the official Saudi tables, while the tabular calendars follow a fixed 30-year cycle, so the same Gregorian day can land on neighbouring Hijri dates. In practice the engines stay within a day or two of one another.
