Hijri date converter
Convert between Gregorian and Hijri dates using the Umm al-Qura calendar. Everything runs locally.
How the conversion works
Gregorian to Hijri uses the browser's Umm al-Qura calendar data. Hijri to Gregorian verifies the requested date against that calendar and marks a tabular estimate if the browser has no Islamic calendar support.
Dates are handled in UTC to keep the calendar day stable. This tool is for scheduling and reference, not for religious rulings.
