How are prayer times calculated for Gloucester?
Sitting at roughly 51.86°N in Gloucestershire, Gloucester has its own sunrise and sunset each day, so its prayer times are worked out from its exact position rather than a regional average.
Today the sun rises at 07:47 and Maghrib falls at 17:58, giving 10h 11m between the two. As the year turns this daylight window lengthens and shortens, which is why Fajr (currently 05:54) and Isha (currently 19:44) shift gradually from week to week.
When praying in Gloucester, the Qibla is faced towards the Kaaba in Makkah, which lies on a bearing of 117° from here, roughly to the south-east — a great-circle distance of about 4,941 km.
