About this digital tool
The Hijri–Gregorian converter converts dates between the Islamic (Hijri, lunar) calendar and the Gregorian (solar) calendar in both directions. Enter a Gregorian date and get the Hijri date, or enter the Hijri year, month and day and get the Gregorian date. The tool also shows today's Hijri date.
The Hijri calendar has 12 lunar months and about 354 days a year, so 10-11 days fewer than the Gregorian year, which is why Islamic observances such as Ramadan and the Eids move each year in the Gregorian calendar. The conversion uses an arithmetic algorithm, so it can differ by a day from the officially announced date, which depends on the sighting of the moon. For religious holidays, follow the announcements of the relevant community.
How to use
- Enter the Gregorian date to get the Hijri date.
- Or enter the Hijri date to get the Gregorian date.
- The conversion works in both directions.
