How are prayer times calculated for Belfast?
Belfast lies at a latitude of about 54.60°N, in County Antrim. 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 08:06 and Maghrib falls at 18:09, giving 10h 3m between the two. As the year turns this daylight window lengthens and shortens, which is why Fajr (currently 06:06) and Isha (currently 20:02) shift gradually from week to week.
When praying in Belfast, the Qibla is faced towards the Kaaba in Makkah, which lies on a bearing of 115° from here, roughly to the south-east — a great-circle distance of about 5,296 km.
Prayer times in Belfast are very close to those in neighbouring towns, though they differ by a minute or two with distance. Nearby you can also check Glasgow (177 km), Carlisle (194 km) and Blackpool (207 km).
