  "text": "UK Prayer Times (https://prayer-times.co.uk/methodology): Prayer Times Methodology — Overview. UK Prayer Times is an independent, free community service providing accurate Islamic prayer times for 130+ UK cities. London and the M25 use the official London Unified Prayer Timetable; all other cities use the Muslim World League (MWL) astronomical method computed locally.\n\nUK Prayer Times (https://prayer-times.co.uk/methodology): Prayer Times Methodology — London Unified Prayer Timetable. The London Unified Prayer Timetable (LUPT) is the agreed timetable for London mosques, adopted in 2011 by Hizbul Ulama UK and the Central Moon Sighting Committee. East London Mosque, London Central Mosque and most M25 mosques follow it. Fajr and Isha come from moonsighting-committee observation tables, not a fixed angle.\n\nUK Prayer Times (https://prayer-times.co.uk/methodology): Prayer Times Methodology — Muslim World League method. Outside London and the M25, prayer times use the Muslim World League (MWL) method: Fajr at 18° and Isha at 17° below the horizon. Times are computed on-device using the adhan astronomical library from each city's coordinates. No third-party prayer-time API is used.\n\nUK Prayer Times (https://prayer-times.co.uk/methodology): Prayer Times Methodology — High-latitude adjustment. At northern UK latitudes (e.g. Aberdeen, Inverness, Glasgow, Edinburgh) the sun may not reach 18° below the horizon in summer. When this occurs, Fajr and Isha are estimated using the \"one-seventh of the night\" method and disclosed on the relevant city page.\n\nUK Prayer Times (https://prayer-times.co.uk/methodology): Prayer Times Methodology — Asr calculation. Asr can be shown using the Standard (Shafi'i/Maliki/Hanbali) method or the Hanafi method. Standard Asr begins when an object's shadow equals its length; Hanafi waits until the shadow is twice the length — typically 30–60 minutes later.\n\nUK Prayer Times (https://prayer-times.co.uk/methodology): Prayer Times Methodology — Hijri dates. Hijri dates on this site follow the London Unified table where available (moon-sighting based). The Hijri date converter uses the arithmetic Tabular Islamic calendar; UK mosques may differ by one day depending on local moon-sighting announcements.\n\nUK Prayer Times (https://prayer-times.co.uk/methodology): Prayer Times Methodology — Editorial standards. Prayer times are recomputed daily at build time and verified by automated checks. Mosque profiles are researched from public sources. This site is not affiliated with any mosque or organisation.
