Which Hijri algorithm?
This tool uses the tabular Umm al-Qura algorithm (via moment-hijri), the official civil calendar of Saudi Arabia and the one most widely used in software. It can differ by a day from a local moon-sighting decision — for religious dates that depend on a moon-sighting committee, verify with your local authority.
Common uses
- Convert a birth date on a Saudi ID to Gregorian
- Book a Gregorian appointment given a Hijri due date
- Plan around Ramadan, Eid, or Hajj dates for scheduling
