How are prayer times calculated for Bolton?
Bolton lies at a latitude of about 53.58°N, in Greater Manchester. 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 07:53 and Maghrib falls at 17:53, giving 9h 59m between the two. As the year turns this daylight window lengthens and shortens, which is why Fajr (currently 05:56) and Isha (currently 19:43) shift gradually from week to week.
When praying in Bolton, 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 5,041 km.
Prayer times in Bolton are very close to those in neighbouring towns, though they differ by a minute or two with distance. Nearby you can also check Bury (9 km), Salford (13 km) and Wigan (14 km).
