How prayer times are calculated

Every time on this site — the page above, the city pages, the JSON API and the MCP server — comes from the same calculation engine that has powered the Quran Majeed app for over two decades, so the website, the mobile apps and the TV apps all show the same minute.

Official timetables come first

676 cities in 19 countries use an official published timetable instead of calculation: among them the London Central Mosque timetable for London, the Ministry of Awqaf timetables for Jordan, government timetables for the United Arab Emirates and Oman, JAKIM and state timetables in Malaysia, Kemenag timetables in Indonesia, the Ministry of Islamic Affairs in Morocco, and mosque-published tables across Europe. Where a timetable exists it always takes precedence over calculation, and the city page names its source. Timetable cities are marked ★ in the directory.

Calculation methods by country

Everywhere else, Fajr and Isha are calculated from the depression of the sun below the horizon, using the method of the country's religious authority. The site picks the method from the city's country automatically; the apps also let you choose any method, or custom angles, yourself.

Dhuhr is solar noon plus a safety margin, and Maghrib is sunset; neither depends on the method above.

Asr

Asr follows the juristic convention: the Shafi’i position (shadow equal to the object) is the default worldwide, and the Hanafi position (shadow twice the object) is applied automatically in Pakistan, India, Bangladesh and Afghanistan. The apps let you switch between the two.

High latitudes

Far from the equator the sun may not reach the Fajr or Isha depression angle at all in midsummer. Times there are bounded by the night itself, using the widely accepted angle-based rule by default (the one-seventh and midnight rules are available in the apps), so Fajr and Isha stay within the night even at the solstices — this is what keeps times sensible in cities like Bern, London, Stockholm or Moscow in June.

Dates, time zones and daylight saving

Times are computed for the city's coordinates in its IANA time zone, with daylight saving applied per day — a timetable for next month already reflects a clock change inside it. Hijri dates follow the Umm al-Qura calendar.

Accuracy

Where an official timetable exists we show it verbatim; where we calculate, the method is named on the page, so you can always see where a time comes from. Mosques may announce their own congregation times — for Jumu’ah especially, check your mosque.
