How do I read the calendar?

Each day shows its Hijri day number, the Gregorian date of the same civil day and the weekday. The caption names the Hijri month, the Hijri year and the method in use. On a wide screen the month appears as a seven-column grid by weekday. On a small screen it becomes a list with the Hijri day, Gregorian date and weekday side by side.

Use the previous and next buttons to move one month at a time, or choose a Hijri year and month directly. Select any day or its Gregorian date to open it in the Hijri date converter. Today uses the civil date on your device, in the time zone shown on the page. It does not ask for your location.

When you write a date in a note or message, spell out the Gregorian month, as in 19 February 2026. That way nobody reads the day and month in the wrong order.

Why are some months 29 days and others 30?

A Hijri month has 29 or 30 days. The calendar shows the actual length under the method you choose:

  • Umm al-Qura uses a fixed calculated table of month starts. It is a calculation, not a record of a moon sighting.
  • Islamic civil uses arithmetic. Months alternate between 30 and 29 days, and in 11 years of every 30-year cycle the last month, Dhu al-Hijjah, has a 30th day.

Both rules are implemented in the calendar library source code.

When you switch method, the same Hijri month and year stay on screen. The Gregorian dates beside them may shift in some months and match in others.

Planning around Ramadan, Eid or another observance

Many communities start Ramadan, Eid and other occasions from an announcement based on moon sighting or local criteria, and authorities do not always agree. For Ramadan 1447, the Saudi official gazette reported a Supreme Court decision that 18 February 2026 was 1 Ramadan. Dar al-Ifta Egypt announced 19 February as 1 Ramadan, and Diyanet in Türkiye set the first fast on 19 February.

The dates shown here are fixed calculations for each method. They do not change when an authority makes an announcement. What is uncertain for a future month is the date your community will actually observe. Use these dates to plan, and confirm with the authority your mosque or community follows. For daily prayer times, see prayer times.

Does the Hijri date shown in this calendar change at sunset?
No. This calendar matches each Hijri date to a whole civil day and does not calculate a sunset-based current date. Pressing Today uses your device's civil date; months you browse stay as they are. In the evening, the Hijri date your community uses may already be the next day.
Which method should I choose?
Choose the method that the calendar or document you are comparing with actually names. If it does not say, ask its publisher or check your community's reference. Do not rely on a few matching dates: they can coincide across methods and do not show which method the source used.
Why can't I select some days?
The calendar covers Gregorian dates from 1 January 1900 to 31 December 2100. In the Hijri months that cross those dates, days outside the range are unavailable. They are not estimated.
