Common questions
Why do Hijri calendar dates differ by 1-2 days between countries?
The Islamic calendar is strictly lunar. Some regions follow astronomical calculation (such as the Umm al-Qura calendar of Saudi Arabia), while others require physical naked-eye or telescope sightings of the new crescent moon (Hilal). This tool provides an offset selector to match your local community.
How many days are in a Hijri year?
A Hijri lunar year consists of 12 lunar months totaling either 354 or 355 days, making it approximately 10 to 12 days shorter than the solar Gregorian year.
What does AH stand for in Islamic dates?
AH stands for 'Anno Hegirae' (in the year of the Hijrah), marking the migration of Prophet Muhammad (PBUH) from Mecca to Medina in 622 CE.
Can I convert historical dates from centuries ago?
Yes, the astronomical Julian Day Number algorithm supports date conversions back to 1 AH (622 CE).
