Umm al-Qura calendar

How it works
This converter uses the Umm al-Qura calendar via the browser's built-in Intl.DateTimeFormat API. For Gregorian → Hijri, the Gregorian date is formatted directly in the Islamic calendar. For Hijri → Gregorian, the tool estimates a starting Gregorian date from the Hijri epoch (1 Muharram 1 AH ≈ 622-07-19 CE) and the average Hijri year length, then nudges day by day until the formatted Hijri date matches your input exactly.
