The Hijri Calendar (Islamic Lunar Calendar)

The Hijri calendar, also called the Islamic calendar or the lunar Hijri calendar, is the calendar used across the Muslim world to date religious events, festivals, and fasting. It counts years from the Hijra — the migration of the Prophet Muhammad (peace be upon him) from Mecca to Medina in 622 CE. This free Hijri calendar converter shows you today's Islamic date and converts any date between the Hijri and Gregorian calendars instantly, right in your browser.

How the Islamic Calendar Works

The Hijri calendar is purely lunar, based on the cycles of the moon. A year contains 12 months and about 354 days — roughly 11 days shorter than the Gregorian solar year. This is why Islamic dates such as Ramadan, Eid al-Fitr, Eid al-Adha, and Ashura move about 11 days earlier each Gregorian year, gradually shifting through all the seasons. The twelve Hijri months are Muharram, Safar, Rabi al-Awwal, Rabi al-Thani, Jumada al-Awwal, Jumada al-Thani, Rajab, Sha'ban, Ramadan, Shawwal, Dhu al-Qi'dah, and Dhu al-Hijjah, alternating between 29 and 30 days.

Why Use a Hijri Date Converter?

Muslims around the world use the Hijri calendar to know when to fast in Ramadan, when to celebrate the two Eids, when to perform Hajj in Dhu al-Hijjah, and to commemorate important Islamic occasions. A reliable converter helps you plan ahead, fill out official documents, mark birthdays and anniversaries in the Islamic date, and stay connected to the rhythm of the Islamic year. This tool uses a standard arithmetic Hijri calculation, so results are consistent and instant — note that the exact start of some months may vary by a day depending on local moon sighting.
