Gregorian to Hijri Date Converter

أهلاً و سهلاً (welcome)

This website's purpose is to help people convert dates between the gregorian calendar and the hijri or islamic calendar. There is also a special tools for web developers: a Unix timestamps conversion tool and an API. hijri-tools.cc is based on Hijri.js, a small JS library that can be found here. It uses the Saudi calendar commonly called "Umm al-Qura".

What is a Hijri calendar ?

The Hijri calendar is the Islamic lunar calendar, which started with the migration (Hijrah) of the Prophet Muhammad ﷺ from Makkah to Medina in 622 CE. It is made up of 12 lunar months and is about 11 days shorter than the Gregorian solar calendar. In short, a hijri calendar is the islamic calendar.

In the Islamic calendar, each month begins with the sighting of the new moon, marking the start of a new lunar cycle. Historically, this has been determined by the actual observation of the moon's crescent (known as the hilal), which signals the end of the previous lunar month and the start of the new one. As a result, the length of each month can vary—either 29 or 30 days—depending on factors like the moon's visibility, Earth's astronomical position, and weather conditions. Among the twelve months of the Hijri calendar, four are regarded as sacred: Rajab (the 7th month), as well as the three consecutive months of Dhū al-Qa'dah (11th), Dhu al-Ḥijjah (12th), and Muḥarram (1st).

Please remember that Hijri dates may vary by country or region due to differences in moon sighting. This website operates using Eastern Standard Time.
