Gregorian to Hijri Date Converter
Convert a Gregorian date to the Hijri (Islamic) calendar.
Enter your values to calculate your result.
The Hijri date shown here is a calculation aid based on the tabulated Umm al-Qura calendar and may differ by a day from a date announced locally based on moon sighting. It is not a religious ruling.
Formula
Converts using the tabulated Umm al-Qura calendar — the same calendar Saudi Arabia uses as its civil calendar — rather than a generic fixed-pattern (arithmetic) Hijri calendar.
Frequently Asked Questions
Why might this differ from my local mosque's calendar?
Many communities confirm the start of a Hijri month by local moon sighting, which can fall a day before or after the tabulated Umm al-Qura date used here.
What date range is supported?
Gregorian dates from November 12, 1882 to November 16, 2077 (Hijri years 1300-1500), the range with reliable Umm al-Qura tabulated data.
