How are prayer times calculated for Derby?
Sitting at roughly 52.92°N in Derbyshire, Derby 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 07:44 and Maghrib falls at 17:55, giving 10h 10m between the two. As the year turns this daylight window lengthens and shortens, which is why Fajr (currently 05:49) and Isha (currently 19:43) shift gradually from week to week.
When praying in Derby, the Qibla is faced towards the Kaaba in Makkah, which lies on a bearing of 119° from here, roughly to the south-east — a great-circle distance of about 4,950 km.
Prayer times in Derby are very close to those in neighbouring towns, though they differ by a minute or two with distance. Nearby you can also check Burton upon Trent (17 km), Nottingham (22 km) and Mansfield (31 km).
