Hijri Calendar Converter
Convert between the Gregorian (civil) calendar and the Hijri (Islamic lunar) calendar. Hijri dates are based on moon sighting conventions that can vary slightly by country and authority, so treat the result as a close standard calculation rather than a single universally agreed date, especially near the start or end of a lunar month.

Calculating today's Hijri date...
Conversions are calculated astronomically by the AlAdhan API and will typically match widely used civil Hijri calendars. Local moon-sighting announcements by national or regional Islamic authorities, which determine the actual start of months like Ramadan and Shawwal, can fall a day earlier or later than this calculation. Always follow your local mosque or national authority's announcement for religious observances.
