Why the Umm al-Qura calendar?
Umm al-Qura is the official Hijri calendar of Saudi Arabia and is used on government documents and contracts. Its months are set in advance from astronomical calculations for Makkah, which is why the Hijri date of any day can be known years ahead.
Religious occasions such as the start of Ramadan and the two Eids are confirmed after the new crescent is sighted, and the announcement can differ from the calculated calendar by a day. Our countdowns say so clearly and treat those dates as estimates.
Accuracy and privacy
Date conversion uses the Umm al-Qura tables built into modern browsers (the Intl API), and prayer times come from the open-source adhan library. We checked the converter day by day from 1900 to 2076 to make sure conversions round-trip exactly.
No tool needs an account, and nothing you enter is stored. If you let your browser share your location for prayer times or the Qibla, the coordinates are used on your device only.
Frequently asked questions
Are these tools free?
Yes. Every tool in this section is free and works without signing up or installing an app, on phones and computers.
Which Hijri calendar do you use?
The Umm al-Qura calendar, the official calendar of Saudi Arabia. Other countries may differ by a day where they rely on local moon sighting.
How are prayer times calculated?
Astronomically, from the city’s coordinates and the date. Saudi cities use the Umm al-Qura method by default; other cities use the method common in their country, and you can change the method and the Asr rule.
Is there an Arabic version?
Yes. Every page has an Arabic version — use the العربية button at the top of the page.
Do the tools work offline?
Once a page has loaded, the calculations run in your browser, so clocks, timers and the stopwatch keep working if your connection drops.
