FAQ about Hijri-Gregorian Date Conversion
Enter the Hijri date (day, month, year) in the designated fields and click the convert button. The result will show the corresponding Gregorian date with the day name. Conversion uses the Umm al-Qura algorithm officially adopted in Saudi Arabia.
The Umm al-Qura calendar is the official Hijri calendar adopted in Saudi Arabia. It is issued by the Astronomy and Geophysics Research Institute at King Abdulaziz City for Science and Technology. It relies on precise astronomical calculations to determine the beginning of each Hijri month based on crescent moon sighting.
The Hijri date may differ between countries for several reasons: different methods for determining the start of the month (naked eye sighting vs astronomical calculation), different geographical locations affecting crescent visibility, and different scholarly references followed. This is why Ramadan or Eid may start a day or two apart between countries.
The Hijri year is about 11 days shorter than the Gregorian year. A Hijri year = 354 or 355 days, while a Gregorian year = 365 or 366 days. Therefore, approximately every 33 Gregorian years equals 34 Hijri years. You can estimate conversion with: Gregorian year = Hijri year × 0.97 + 622.
