How the Hijri calendar works
The Islamic calendar is lunar: months begin with the sighting of the new crescent. Over time, it shifts relative to the solar Gregorian calendar. Religious dates (e.g., Ramadan, Eid) depend on local announcements.
Why dates can vary by country
Some authorities follow local physical sighting; others accept regional or astronomical criteria. This can shift dates by a day compared to other countries. Always follow official announcements in your location.
Converter usage tips
- Use the converter for planning, but defer to local announcements for religious observances.
- Be aware of the 1‑day variance across regions.
