Salah times in United Kingdom.

The United Kingdom is home to around 4 million Muslims, about 6.5% of its 67-million population — one of the largest Muslim communities in Western Europe. The community is exceptionally diverse: Pakistani and Kashmiri British communities form the largest group, alongside substantial Bangladeshi, Somali, Arab, Turkish, North African, Indian, and white convert Muslim communities. The first purpose-built mosque in the UK was the Shah Jahan Mosque in Woking, built in 1889; today some of the largest mosques in Western Europe — including the Baitul Futuh in Morden and the East London Mosque — sit alongside countless neighbourhood mosques in cities such as Birmingham, Bradford, Manchester, and Glasgow. UK prayer times are typically calculated using the Muslim World League or ISNA method, with local timetables (notably the London Unified Prayer Timetable) widely used. The UK observes Greenwich Mean Time (UTC+0, shifting to BST UTC+1 in summer) and at 50–58° north sees dramatic seasonal Fajr and Isha variation.
