The Umm al-Qura calendar
Saudi Arabia uses the Umm al-Qura calendar for official Hijri dates. These tools use its month table for 1365–1500 AH (1945–2077) and show no result outside that range rather than guess with an approximate calendar.
A Hijri year has 354 or 355 days, about 11 days fewer than a Gregorian year, so each Hijri date falls about 11 days earlier every Gregorian year. Dates before 1392 AH can differ by a day between published tables, and the converters say so.
Frequently asked questions
Which Hijri calendar do you use?
The Umm al-Qura calendar, used for official dates in Saudi Arabia.
How do I read the month calendar?
Each box is one Hijri day: the large number is the Hijri day and the small number under it is the Gregorian date. Fridays and Saturdays are shaded. Use the arrows to move between months, or pick a month from the table below the calendar.
Why can the start of a month differ from what was announced?
Religious occasions such as Ramadan and the Eids follow moon sighting, which can move the start by a day. Civil dates follow the Umm al-Qura calendar.
What is today's date based on?
Today's date is taken from the current time in Riyadh, so it changes at midnight Saudi time.
Why do Hijri dates move against the Gregorian calendar?
The Hijri year is lunar, about 354 days, so each Hijri date comes around 11 days earlier every Gregorian year. Ramadan works its way through every season in about 33 years.
