Gregorian to Hijri Date Converter

How to convert a Gregorian date to Hijri

Select the day, month and year in the Gregorian calendar and press Convert. The result shows the Hijri day, the name of the Islamic month and the Hijri year, together with the weekday.

The converter accepts dates from the year 623 onward, so it covers everything from the first years of Islam to dates centuries ahead.

Find your Hijri date of birth

One of the most common reasons to use this page is to find a birthday in the Islamic calendar. Enter your Gregorian date of birth and you will get the Hijri date you were born on.

Bear in mind that the Islamic day starts at sunset, not at midnight. If you were born in the evening after Maghrib, your Hijri birth date is the day after the one shown. You can get it by converting the following Gregorian day.

Because the Hijri year is shorter, your Islamic birthday moves about 11 days earlier in the Gregorian calendar each year, and your age in Hijri years is slightly higher than your age in Gregorian years. Someone who is 33 by the Gregorian calendar is about 34 by the Hijri one.

Planning ahead with the Islamic calendar

Converting Gregorian dates to Hijri helps when you are planning around the Islamic year: checking which Hijri month a holiday or trip falls in, working out when a lunar year has passed for zakat, or seeing how far away Ramadan is.

Future dates are calculated in advance by the Umm al-Qura calendar. Where the month is confirmed by sighting the crescent, the real date may turn out one day later, so treat future dates as a close guide and confirm them nearer the time.
