Understanding both calendars
Calendrier solaire grégorien et calendrier lunaire hégirien
Le Calendrier Solaire Grégorien
The Gregorian calendar is solar: it tracks Earth's orbit around the Sun (roughly 365.2425 days per year). It serves as the international civil standard for official and financial records.
Le Calendrier Lunaire Hégirien
The Hijri calendar is strictly lunar: it consists of 12 lunations (months of 29 or 30 days), totaling 354 or 355 days. It started on 1 Muharram AH 1 (July 16, 622 CE), commemorating the Prophet Muhammad's migration from Mecca to Medina.

Frequently Asked Questions: Hijri & Gregorian Dates
Why does the Hijri year have 354 or 355 days?
The Islamic calendar follows moon phases strictly. A lunar synodic month lasts about 29.53 days, alternating between 29 and 30 days. Twelve lunar months total 354 days (or 355 days in leap years), which is 10 to 11 days shorter than the solar Gregorian year. This explains why holidays like Ramadan shift earlier across seasons year after year.
How does the lunar adjustment slider work (-2 to +2 days)?
In Islamic tradition, the start of each lunar month requires confirmed sightings of the new crescent moon (hilal). Depending on geographic location, weather, and decisions by local religious councils, dates may vary by 1 or 2 days from mathematical tables. Our adjustment slider lets you easily align with your local country's official sighting.
When did the Hijri calendar start?
Caliph Umar ibn al-Khattab established the calendar in 638 CE. He set the initial epoch as 1 Muharram of year 1 AH, corresponding to July 16, 622 CE in the Julian calendar, marking the Prophet's Hijrah (migration) to Medina.
