The calculation method, the Asr question, and how to get London’s times right — without guessing.
Fajr 18°, Isha 17° is common, but London mosques differ: some use Umm al-Qura, some the 18.5° angle. There is no single agreed convention.
Both exist. The major Hanafi mosques (East London Mosque, others) follow Asr at twice the shadow length; others use Shafi’i.
London is above 48° latitude, where summer twilight never fully fades. Mosques adopt one of several high-latitude rules for Fajr and Isha in midsummer — ask your mosque which it uses.
