Convert dates between the Gregorian (Western) calendar and the Hijri (Islamic) calendar. The Hijri calendar is a lunar calendar used to determine Islamic holidays and events.
Convert dates between Gregorian and Hijri calendars, free. A calendar converter translates a date between the Gregorian (civil) calendar and the Hijri (Islamic lunar) calendar in both directions. It's used to find the Islamic date for a Gregorian day — or vice versa — for holidays, records, and planning, and it runs entirely in your browser.
It converts both ways between Gregorian and Hijri dates, so you can look up an Islamic date for any civil day or place a Hijri date on the civil calendar. 100% free, no registration, and complete privacy — everything runs locally in your browser, so your data never touches a server.
Convert Gregorian → Hijri or Hijri → Gregorian with one tool.

Enter a date and read the converted date immediately, no lookup tables.
Conversion runs locally; nothing is uploaded.
The Hijri (Islamic) calendar is lunar: 12 months of 29–30 days totalling about 354 days, so it is roughly 11 days shorter than the 365-day Gregorian solar year. That's why Islamic dates move earlier through the seasons each year.
The Islamic calendar can be based on calculation (tabular) or on actual moon sighting, which varies by region. A calculated converter may differ by a day from a locally sighted date — confirm with your local authority for religious observances.
