Prayer Times Calculator
Umm al-Qura, Muslim World League, ISNA and more: calculated prayer times for any city, with the next prayer countdown. An estimate: check your local mosque for congregational times.
Times are calculated from the sun position for the coordinates above, using the method you picked. They are an estimate, usually within a few minutes of a published timetable. For congregational prayer, follow your local mosque or the official Umm al-Qura calendar. Umm al-Qura uses 90 minutes after Maghrib for Isha, and 120 minutes during Ramadan: change the Isha field to 120 in Ramadan.

Fajr uses the angle shown above. Dhuhr is solar noon for the location. Maghrib is sunset. If any time looks wrong for your city, check the latitude, longitude and UTC offset first: a wrong offset shifts every time by the same amount.
Why prayer times differ between apps
Every prayer time comes from the position of the sun, but the exact line each method draws is different. Fajr is set by how far below the horizon the sun sits at true dawn, and Isha by how far below it sits after sunset. Umm al-Qura, the method used for the official calendar in Saudi Arabia, puts Fajr at 18.5 degrees below the horizon and sets Isha at a fixed 90 minutes after Maghrib (120 minutes in Ramadan) instead of using an angle at all. The Muslim World League uses 18 degrees for Fajr and 17 for Isha. ISNA uses 15 and 15. A change of one degree moves Fajr or Isha by roughly 4 to 5 minutes, which is why two apps can disagree and both be following a real method.
Asr is the other split. Most schools start Asr when an object's shadow equals its own length plus the noon shadow. The Hanafi school starts it when the shadow equals twice the object. That puts Hanafi Asr about 30 to 45 minutes later. This calculator lets you pick the school, the method, and every angle, so you can match the timetable your own mosque follows.
Calculated, not copied
No timetable is fetched from anywhere. The page computes the sun position for your date and coordinates in your browser, so it works for any city and any date, past or future. The trade-off is honest: a computed time can sit a few minutes away from an official calendar that applies local adjustments.
Next prayer countdown
Once calculated, the page names the next prayer and counts down to it, updating every minute. Pick today's date and your city, and the countdown runs from the times on screen.
How to use this calculator
- Pick your city, or type your own latitude, longitude and UTC offset.
- Pick the calculation method your mosque uses. Umm al-Qura is the default for Saudi Arabia.
- Pick the Asr school. Change the Isha field to 120 during Ramadan for the Umm al-Qura method.
- Calculate, then compare one day against your mosque timetable. If every time is off by the same amount, the UTC offset is wrong.
