How are prayer times calculated for Chatham?
Chatham lies at a latitude of about 51.38°N, in Kent. 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 07:33 and Maghrib falls at 17:50, giving 10h 16m between the two. As the year turns this daylight window lengthens and shortens, which is why Fajr (currently 05:42) and Isha (currently 19:35) shift gradually from week to week.
When praying in Chatham, the Qibla is faced towards the Kaaba in Makkah, which lies on a bearing of 120° from here, roughly to the south-east — a great-circle distance of about 4,747 km.
Prayer times in Chatham are very close to those in neighbouring towns, though they differ by a minute or two with distance. Nearby you can also check Gillingham (2 km), Maidstone (12 km) and Gravesend (13 km).
