How are prayer times calculated for Grimsby?
Grimsby lies at a latitude of about 53.57°N, in Lincolnshire. 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 07:44 and Maghrib falls at 17:43, giving 9h 59m between the two. As the year turns this daylight window lengthens and shortens, which is why Fajr (currently 05:46) and Isha (currently 19:34) shift gradually from week to week.
When praying in Grimsby, the Qibla is faced towards the Kaaba in Makkah, which lies on a bearing of 121° from here, roughly to the south-east — a great-circle distance of about 4,905 km.
