About the Hijri Date Converter
Hijri Date Converter changes a Gregorian date into the Islamic (Hijri) date and back again. Pick a date and the page gives the Hijri day, month name and year with the day of the week, or enter a Hijri date and it finds the Gregorian date. It uses the Umm al-Qura calendar, the official calendar of Saudi Arabia, from your browser's own date data, and covers the Hijri years 1300 to 1600. Use it for Ramadan and Eid dates, birthdays, documents and family history.

Two calendars, two systems
The Gregorian calendar follows the sun and has 365 or 366 days. The Hijri calendar follows the moon with 12 months of 29 or 30 days, a total of 354 or 355 days. Because of this, Islamic dates move about 11 days earlier each Gregorian year, and Ramadan falls in every season over a period of about 33 years.
Finding important dates
To find Ramadan, choose Hijri to Gregorian, enter the year, pick month 9 (Ramadan) and day 1. Eid al-Fitr is 1 Shawwal, Eid al-Adha is 10 Dhu al-Hijjah and the Islamic New Year is 1 Muharram. Remember that the real start of Ramadan depends on the moon sighting in your country, so the date may be a day earlier or later.
- 1 Muharram: Islamic New Year
- 1 Ramadan: first day of fasting
- 1 Shawwal: Eid al-Fitr
- 10 Dhu al-Hijjah: Eid al-Adha
Use it for documents and family history
Saudi documents, school records, old certificates and Quran manuscripts are often dated in Hijri. A converter makes it easy to write both dates side by side. When you write a date for an official form, check which calendar the form asks for.

Frequently asked questions
What is the Hijri calendar?
The Islamic calendar, a lunar calendar of 12 months of 29 or 30 days that began in 622 CE, the year of the Hijra. A Hijri year is about 354 or 355 days, so its months move earlier through the seasons.
What is Umm al-Qura?
The calendar used in Saudi Arabia, based on astronomical calculations rather than on moon sighting. It is the standard for official dates and for many online converters.
Why can the date be a day different from my local one?
Many countries start a month when the new moon is sighted locally, which can be a day before or after Umm al-Qura. For Ramadan and Eid, follow your local authority.
What are the Hijri months?
Muharram, Safar, Rabi' al-awwal, Rabi' al-thani, Jumada al-ula, Jumada al-akhira, Rajab, Sha'ban, Ramadan, Shawwal, Dhu al-Qa'dah and Dhu al-Hijjah.
When does the Hijri day begin?
At sunset, but civil conversions use midnight, as this page does. The evening before a date is in the Islamic day that follows.
