Prayer Time Accuracy Checks

These dated checks compare our default calculated prayer starts with mosque-published or media timetables. They measure agreement with a publisher, not proof of astronomical or religious correctness.

Read the evidence before choosing a timetable

Difference = SalahTable minus publisher, in minutes: positive means later. A mean can hide larger daily differences, so the tables also show the largest absolute difference and the number of available samples for each prayer. We compare start columns, not iqamah or Jumu‘ah schedules.

Karachi uses a newspaper reference because an official local timetable was not verified for these checks. New York is a single dated snapshot from Masjid Manhattan; the date displayed by the source was 2 November, even though it was retrieved on 3 November. London includes November and December only, so this does not validate summer twilight.

Limits and reproducibility

Coordinates, rounding, offsets and adopted dawn or twilight conventions can differ. London Fajr and Isha exceed a two-minute agreement threshold in this sample; that result is shown rather than labelled a pass. Do not extend a winter result to summer or a one-day result to a whole year.

The machine-readable summary records version 2026-11-03, source links, retrieval dates and counts. These checks reuse the site's dated regression fixtures. Publisher schedules remain the publishers' material; the CC BY license on our research does not relicense their original timetables.

See calculation methodology and why timetables differ. For congregation times and adopted local practice, consult your mosque.
