Hijri Date Converter

The Hijri calendar is the lunar calendar used by Muslims to determine Islamic dates, festivals and religious observances. It consists of 12 months and is approximately 354 days long, so dates shift earlier by 10-11 days each Gregorian year.

This free converter takes any Gregorian date and returns the equivalent Hijri date. It uses the standard astronomical conversion from the hijri-converter library. Note that regional crescent sighting (rukyah) can shift the actual Hijri date by one day in some countries.

Important: For religious decisions, confirm the date with your local mosque or crescent sighting committee.
