United Kingdom prayer times

Britain has no single national prayer timetable. This page explains which table the app serves for UK cities, how it compares with the London and mosque timetables many people use, and where the two will differ.

Calculation and source

Institution
No national authority
Method
Diyanet
The timetable Diyanet publishes for 154 UK settlements; the calculation fallback uses Fajr 18° / Isha 17°.
Asr
The app’s default Asr for the United Kingdom is the Hanafi shadow ratio of two, which is the convention most British mosque timetables print.
Precaution minutes
None. The app adds no precaution minutes of its own.
Time zone
The clocks go forward on the last Sunday in March and back on the last Sunday in October. Prayer times follow the sun, so the printed clock times jump by an hour on both weekends; only the clock moves, not the prayer. Scotland sits far enough north that the summer gap between maghrib and isha becomes very short, and in Glasgow and Edinburgh the isha angle is reached only just before dawn in June.
Hijri calendar and crescent
Ramadan and the two Eids are announced separately by mosques and councils in Britain. Some follow local sighting, some follow Saudi Arabia, some follow a calculated calendar, and the start date can differ by a day between two mosques in the same city. The Hijri date in the app is calculated and may not match the day your mosque announces.

Prayer times in Britain are set mosque by mosque and city by city; the most widely followed published table is the London Unified calendar of the East London Mosque, the London Central Mosque and the Islamic Cultural Centre.

United Kingdom prayer times

Why there is no single British timetable

Unlike Türkiye, Malaysia or Singapore, Britain has no body with the standing to publish one prayer timetable for the country. What exists instead is a set of respected local calendars. The best known is the London Unified calendar, agreed between the East London Mosque, the London Central Mosque and the Islamic Cultural Centre, and it is printed in mosques far beyond London. Alongside it sit city calendars in Birmingham, Bradford, Leicester and Glasgow, and individual mosque timetables that may adjust fajr and isha by several minutes. None of these is official in the sense that a government has endorsed it; they are conventions that communities have agreed on.

What this site shows for British cities

For each of the cities listed below, the app serves the timetable that the Turkish Presidency of Religious Affairs publishes for that settlement. Diyanet prints times for 154 places in the United Kingdom, and every city page on this site was checked against the institution’s own published row for the same day; all six times matched in all fifty cities. That is what the label on each row means. It does not mean Diyanet is a British authority, and it does not mean your mosque uses the same table. London is the one exception on the English pages: for any month the London Unified calendar has been published and verified, the London page shows that calendar instead, and its rows say “London Unified Prayer Timetable”.

Fajr, isha and the British summer

The hardest part of a British timetable is not noon or sunset but the two ends of the night. Above roughly 48 degrees of latitude the sun does not sink far enough below the horizon in midsummer for the usual fajr and isha angles to be reached at all, and every calendar has to choose a rule for those weeks. The London Unified calendar and the Diyanet table resolve this differently, which is why the largest disagreements between British timetables appear in June and July and why two neighbouring mosques can print isha times half an hour apart. Around the equinoxes, in late March and late September, the tables converge again.

Selecting a mosque timetable instead

If your mosque’s calendar is the one you pray by, the app lets you select an institution timetable rather than the default. Cambridge Central Mosque’s published annual timetable is available as an explicit choice: selecting it switches the times to that mosque’s own table for the dates it published, with no minutes added. The claim attached to a profile is narrower than a country claim: it holds while the selected published timetable is used, and it is not extended to places the institution did not publish for.

Questions

Why is the app’s isha different from my mosque’s?
British mosques do not share one isha convention. The angle used, whether a fixed interval after maghrib is applied in summer, and whether the mosque adds precaution minutes all change the printed time. Compare the same date in both tables before assuming one is wrong; if you follow a specific mosque, select its timetable in the app where one is available.
Is Diyanet an official source for the United Kingdom?
No. Diyanet is the Turkish state institution for religious affairs, and it publishes a timetable for settlements in many countries including Britain. Britain has no national prayer-time authority, so no timetable here can be called the official one. The app serves the Diyanet table and says so on every row.
Do the times change when the clocks change?
The clock times shift by an hour on the last Sundays of March and October, because British Summer Time moves the clock, not the sun. The app reads the time zone for each city, so the change is handled automatically and no setting needs to be adjusted.
