Hijri Date Converter

How to convert a Gregorian date to Hijri, and Hijri to Gregorian

There are two cards at the top. The first converts a Gregorian date to Hijri, which is what most people need: they know the everyday date and want the Hijri one. The second goes the other way. Each card works on its own, so use both if you need to.

• Type the day in the first field.
• Pick the month from the list. Month names are written out in full.
• Type the year, for example 2026 for Gregorian or 1448 for Hijri.
• The result appears straight away with the day of the week. You can copy it or send it on WhatsApp.

What is the Umm al-Qura calendar?

Umm al-Qura is the official Hijri calendar of Saudi Arabia, published by the King Abdulaziz City for Science and Technology. It sets the start of each month with an astronomical calculation of the moon's position at Makkah, so its dates are known years in advance.

Saudi government bodies use it for official dates, and this tool uses it too. It covers 1318 AH to 1500 AH, roughly 1900 CE to 2077 CE.

Why can a date be off by one day?

If another website gives you a date one day apart, it is probably using a different method, such as the simplified civil Hijri calendar, or following moon sighting in another country.

The same can happen with Ramadan, Shawwal and Dhu al-Hijjah. Their start is announced after the crescent is sighted and can differ by a day from the calculated calendar. If you need the date for an official procedure or a religious occasion, confirm it with the relevant authority.

When do you need to convert a date?

These are the most common reasons people convert between Gregorian and Hijri dates:

• Filling in a form that asks for a Hijri date of birth when you only know the Gregorian one.
• Reading an old contract, deed or document written in Hijri.
• Matching dates on academic or employment certificates.
• Working out when rent, an instalment or a policy falls due.
• Finding which Gregorian day matches a Hijri one, such as 1 Ramadan or the Day of Arafah.

Hijri year vs. Gregorian year

The Hijri year is lunar and has 354 or 355 days. The Gregorian year is solar and has 365 or 366. Hijri occasions therefore move about 11 days earlier each Gregorian year, and Ramadan travels through all the seasons roughly every 33 years.

The Hijri calendar starts from the Prophet's migration from Makkah to Madinah in 622 CE. For a quick estimate of the year without the tool, the Gregorian year is about the Hijri year × 0.97 + 622. That only gives the year, roughly. For the exact day and month, use the converter.

Hijri months and Gregorian months

A Hijri month has 29 or 30 days, depending on the crescent.
