Hijri Calendar Guide
Understanding the Islamic calendar
The Hijri calendar is a purely lunar calendar — 12 months tracked strictly by the moon's cycle, with no leap-year adjustment to stay aligned with the solar year, unlike the Gregorian calendar. A Hijri year runs 354 or 355 days. It begins its count from the Hijra — the Prophet Muhammad ﷺ's migration from Makkah to Madinah in 622 CE — and governs when Ramadan, Eid, Hajj, and other Islamic observances fall each year.
