Islamic Calendar

Hijri dates begin at sunset the evening before, and the exact local start of each month can vary by a day depending on moon sighting.

This is a calculation tool based on the Umm al-Qura calendar, not a fatwa — local moon-sighting announcements may shift a date by a day. Laylat al-Qadr's exact night is not fixed by any calendar; the 27th of Ramadan is shown as the most commonly observed estimate.

Hijri/Gregorian conversion by AlAdhan.com (Umm al-Qura method) — the same service used for the Prayer Times page.
