About Hijri ↔ Gregorian conversion
Convert any date between the Gregorian and the Hijri (Islamic) calendars used across the Gulf.
The Hijri calendar is lunar — 12 months of 29 or 30 days — so the Islamic year is about 11 days shorter than the Gregorian year.
This converter uses the tabular (arithmetic) civil calendar, so official moon-sighting dates may differ by a day.
Choose a direction, enter your date, and the converted date with its weekday appears instantly.
For religious observances, always confirm dates with an official moon-sighting authority.
