About this calculator
The Hijri calendar is lunar: each month starts with the new moon and has 29 or 30 days, so a Hijri year is about 354 days — around 11 days shorter than a Gregorian year. This converter uses Umm al-Qura, the official calculated calendar of Saudi Arabia, from your browser’s calendar data. Religious dates such as the start of Ramadan are confirmed by moon sighting and can differ from the calculated date by a day.
Worked example
1 January 2027 in the Umm al-Qura calendar is 23 Rajab 1448 AH. Going the other way, 1 Ramadan 1448 AH falls on Monday, 8 February 2027.
