How are prayer times calculated for Basildon?
Sitting at roughly 51.58°N in Essex, Basildon 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 07:34 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 Basildon, 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 4,760 km.
