How are prayer times calculated for Norwich?
Sitting at roughly 52.63°N in Norfolk, Norwich 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 07:34 and Maghrib falls at 17:42, giving 10h 7m between the two. As the year turns this daylight window lengthens and shortens, which is why Fajr (currently 05:39) and Isha (currently 19:30) shift gradually from week to week.
When praying in Norwich, the Qibla is faced towards the Kaaba in Makkah, which lies on a bearing of 122° from here, roughly to the south-east — a great-circle distance of about 4,773 km.
Prayer times in Norwich are very close to those in neighbouring towns, though they differ by a minute or two with distance. Nearby you can also check Ipswich (65 km), Colchester (87 km) and Cambridge (93 km).
