How are prayer times calculated for Exeter?
Sitting at roughly 50.72°N in Devon, Exeter 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 07:50 and Maghrib falls at 18:05, giving 10h 15m between the two. As the year turns this daylight window lengthens and shortens, which is why Fajr (currently 06:00) and Isha (currently 19:49) shift gradually from week to week.
When praying in Exeter, the Qibla is faced towards the Kaaba in Makkah, which lies on a bearing of 115° from here, roughly to the south-east — a great-circle distance of about 4,966 km.
Prayer times in Exeter are very close to those in neighbouring towns, though they differ by a minute or two with distance. Nearby you can also check Plymouth (57 km), Cardiff (88 km) and Newport (103 km).
