What time does Suhoor end?
Suhoor ends at the start of Fajr, the beginning of the dawn prayer: from that moment you stop eating and drinking and the fast has begun. There is no fixed clock time. It depends on your latitude, the date, and the Fajr angle your authority uses, so it moves by a minute or two every day and can differ by a quarter of an hour between two timetables for the same city. Generate the timetable above for the city you are actually in rather than borrowing one from elsewhere.
