Ramadan in the UK: The Longest and Shortest Fasts
Britain sits far enough north that the length of a fasting day changes dramatically with the season. A Ramadan falling in June is a very different month from one falling in December, and because the Islamic calendar moves through the solar year, British Muslims experience both over the course of a lifetime.
Two times define the fast
The fast begins when Fajr enters and ends at Maghrib, which is sunset. Suhoor is not a separate prayer time but simply the meal before Fajr. Many timetables print Fajr and Imsak as one line; others subtract a few precautionary minutes for Imsak. Where both appear, the earlier one is the cautious stopping point.
How far apart the seasons are
At London's latitude the gap between sunrise and sunset ranges from under eight hours at the winter solstice to over sixteen and a half in June — and the fast, running from Fajr to sunset, is longer still because Fajr precedes sunrise. Further north the spread is wider again: Glasgow and Edinburgh at around 56 degrees see both longer summer fasts and shorter winter ones than London.
Why the timetables diverge most in summer
In a summer Ramadan, Fajr falls inside the period when the twilight angle is never reached, so the timetable is applying a rule rather than a direct calculation. Different rules give times that can be half an hour apart. This is why mosques in the same city sometimes publish noticeably different suhoor times in June, and why the London unified timetable compresses the night deliberately.
Longitude matters for iftar
Within the same evening, iftar in Belfast comes about twenty-three minutes after London, and Cardiff about twelve minutes after. If you are following a family WhatsApp group spread across the country, the times genuinely differ — take your own city's table rather than the one being shared.
Practical advice
Save your city's monthly table at the start of Ramadan so you are not searching each evening. Check once, at the start, that your app uses the same method as your mosque — for Fajr in a summer Ramadan the difference is large enough to matter. And build a few minutes of margin into iftar planning; the difference between two calendars is usually smaller than the time it takes to get food on the table.
If the timetables around you disagree
This is common in Britain and is not a sign that anyone has made a mistake. Ask at your mosque which timetable they follow; it is a routine question. Following your own community keeps you aligned with the congregational prayers and with the people you break the fast with.
