Formula
The conversion uses the Umm al-Qura calendar: a Gregorian day is matched to its Hijri counterpart, or the Gregorian day matching the entered Hijri date is found.
How it works
Choose the direction
Gregorian to Hijri or the reverse.
Enter the date
Use the Gregorian or Hijri fields depending on direction.
Read the result
The matching date appears with its weekday.
