Frequently Asked Questions
What does AH mean in Islamic dates?
AH stands for Anno Hegirae (Latin for "In the year of the Hijrah"). It marks the start of the Islamic lunar calendar in 622 CE when Prophet Muhammad migrated to Medina.
Can there be a 1-day difference in Islamic dates?
Yes. While astronomical algorithms (like Umm al-Qura) provide exact mathematical dates, traditional Islamic calendar months begin with the physical sighting of the crescent moon (Hilal), which can occasionally vary by ±1 day depending on geographical location.
