How to Convert Calendar
Gregorian → Hijri:
Hijri Year = (Gregorian Year - 622) × 1.0307
Hijri → Gregorian:
Gregorian Year = (Hijri Year ÷ 1.0307) + 622
Important Notes:
- Hijri calendar uses lunar years (354/355 days)
- Gregorian calendar uses solar years (365/366 days)
- Hijri New Year every year is about 11 days behind
- There may be approximate 1-2 day deviations in conversions
Since the Hijri calendar is determined by the movement of the moon, there may be slight differences in some regions.
