How are prayer times calculated for Guildford?
Guildford lies at a latitude of about 51.24°N, in Surrey. Because prayer times depend on the position of the sun at a given location, the timings here are calculated specifically for these coordinates rather than borrowed from another town.
Today the sun rises at 07:39 and Maghrib falls at 17:53, giving 10h 13m between the two. As the year turns this daylight window lengthens and shortens, which is why Fajr (currently 05:48) and Isha (currently 19:37) shift gradually from week to week.
When praying in Guildford, the Qibla is faced towards the Kaaba in Makkah, which lies on a bearing of 118° from here, roughly to the south-east — a great-circle distance of about 4,806 km.
Prayer times in Guildford are very close to those in neighbouring towns, though they differ by a minute or two with distance. Nearby you can also check Woking (9 km), Aldershot (13 km) and Kingston upon Thames (27 km).
