Hijri Date Converter
Convert any date between the Islamic Hijri calendar and the Gregorian calendar.
Gregorian to Hijri
Dates are converted using the tabular (arithmetic) Islamic calendar, which follows a fixed cycle rather than observation. Islamic months begin with the sighting of the new crescent moon, and sighting varies by location — so the date shown here may differ by one day from the date announced by your local moon sighting authority. For the start of Ramadan, Eid and Dhul Hijjah, always follow your local authority.
About the Hijri Calendar
The Hijri calendar (التقويم الهجري) is the Islamic lunar calendar used to determine the dates of Islamic months and observances. It begins from the year of the Hijra — the migration of the Prophet Muhammad ﷺ from Makkah to Madinah in 622 CE.
The Hijri calendar is a purely lunar calendar. Each month begins with the sighting of the new moon. A lunar year contains 12 months and approximately 354 days — about 11 days shorter than the Gregorian solar year. This means Islamic dates move approximately 11 days earlier each Gregorian year.

Why do Islamic dates change each year? +
The Hijri calendar is lunar, with approximately 354 days per year — about 11 days shorter than the Gregorian solar year. This is why Ramadan and Eid fall approximately 11 days earlier each year.
