About the Islamic Calendar tool
The Islamic calendar, also called the Hijri calendar, counts lunar months. Each month begins with the sighting of the new moon, so a year has 354 or 355 days. That is about eleven days shorter than the Gregorian year, which is why Ramadan and the Eids move earlier each year.
This page shows today's Hijri date, converts a Gregorian date to Hijri and back, and lists the main dates such as the start of Ramadan, Eid ul-Fitr, the Day of Arafah, Eid ul-Adha and the Islamic New Year. You can also page through a full year.
The dates shown are calculated, so they can differ by a day from the date your community follows. Many mosques and countries rely on moon sighting. Before you plan a fast or a prayer, confirm the date with your local mosque or Islamic authority.

Tips for good results
- Confirm Ramadan and Eid dates with your local mosque, since sighting practice differs.
- Enter dates in the format the form shows to avoid a wrong conversion.
- Note your zakat date in Hijri terms, since the zakat year is a lunar year.
- Use the holidays list to plan leave from work and school ahead of time.
Common mistakes
- Treating a calculated date as the official start of Ramadan or Eid.
- Expecting the Hijri date to change at midnight. The Islamic day begins at sunset.
- Mixing up the day and month when typing a date.
- Using a Gregorian date in the Hijri box, or the other way round.
Common questions
Why do Ramadan and Eid move every year?
The Hijri year is about eleven days shorter than the Gregorian year, so each date moves about eleven days earlier in the Gregorian calendar each year.
Is the date shown the official date?
No. It is a calculated date. Many communities start months by moon sighting, and the result can differ by a day. Ask your local mosque.
When does the Islamic day begin?
The Islamic day begins at sunset. A date shown for daytime may change after Maghrib in places that follow this practice.
How many months are in a Hijri year?
There are twelve months, from Muharram to Dhu al-Hijjah, each of 29 or 30 days.
Does the converter need an internet connection?
Yes. Conversion uses an online service, so it needs a connection. If it is unavailable the page tells you.
