Hijri Date Converter (Islamic Calendar)

How does the Hijri calendar work?

Each Hijri month begins with the new crescent moon and lasts 29 or 30 days, never 31. Twelve months make a year of about 354 days, roughly 11 days shorter than the Gregorian year. That is why Ramadan and the two Eids come about 11 days earlier every year and slowly move through all the seasons.

The same goes for any date you care about. A Hijri anniversary does not stay on the same Gregorian day: it comes about 11 days earlier each year, and a converter like this one is the easiest way to find it.

The years are counted from the Hijra, the Prophet's migration from Mecca to Medina, which is why years carry the letters AH. The twelve months, in order, are:

1. Muharram
2. Safar
3. Rabi al-Awwal
4. Rabi al-Thani
5. Jumada al-Ula
6. Jumada al-Akhirah
7. Rajab
8. Shaban
9. Ramadan
10. Shawwal
11. Dhu al-Qadah
12. Dhu al-Hijjah

How does this converter work?

The tool uses the Umm al-Qura calendar that is built into modern browsers, based on the Unicode CLDR data. Choose Gregorian to Hijri and pick a date, or choose Hijri to Gregorian and enter a day, month and year. If you enter the 30th of a month that only has 29 days in this calendar, the tool tells you the date does not exist.

Under the result you will find upcoming events with estimated dates: Islamic New Year, the Prophet's Birthday, the first day of Ramadan, Eid al-Fitr, Arafah Day and Eid al-Adha. If your browser is very old and cannot handle the Islamic calendar, the tool will ask you to update it.

A worked example

Gregorian to Hijri: 24 October 2026 converts to 13 Jumada al-Ula 1448.

Hijri to Gregorian: 1 Ramadan 1448 converts to 8 February 2027, and 1 Shawwal 1448, the day of Eid al-Fitr, to 9 March 2027. Count the days from 8 February to 8 March 2027 and you get 29, so Ramadan 1448 has 29 days in this calendar.

Now look one year ahead. 1 Ramadan 1449 converts to 28 January 2028. From 8 February 2027 to 28 January 2028 is 354 days, one Hijri year, which is why Ramadan lands 11 days earlier on the calendar.

Why can dates in the UAE differ by a day?

In the UAE, the start of Ramadan, Eid al-Fitr and Eid al-Adha is confirmed by the moon-sighting committee after the crescent is sought locally. The Umm al-Qura calendar is calculated in advance, so the real date can be a day earlier or later than the one shown here.

Public holidays for the Eids are announced by the government shortly before they begin. Treat the dates below as estimates for planning, not as confirmed holidays.

Tips

• Planning a trip in Ramadan? Read our Ramadan in the UAE guide first. Ramadan 1448 falls in February and March 2027, one of the mildest times of year.
• During Ramadan, the prayer times tool shows Fajr and Maghrib for every emirate, which mark the start and end of the fast.
• Leave a day of slack around Eid when booking flights or time off, since the exact holiday is confirmed late. Our post on UAE public holidays lists the main ones.
• Some calendars and apps use other Hijri calculations, so a date elsewhere may differ by a day from this one.
