How are prayer times calculated for Oldham?
Sitting at roughly 53.54°N in Greater Manchester, Oldham 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 07:48 and Maghrib falls at 17:56, giving 10h 8m between the two. As the year turns this daylight window lengthens and shortens, which is why Fajr (currently 05:51) and Isha (currently 19:46) shift gradually from week to week.
When praying in Oldham, 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 5,020 km.
Prayer times in Oldham are very close to those in neighbouring towns, though they differ by a minute or two with distance. Nearby you can also check Ashton-under-Lyne (6 km), Rochdale (8 km) and Manchester (11 km).
