Ramadan Fasting Hours Around the World
Muslims everywhere fast from dawn to sunset — but the length of that fast varies hugely by location, from about 11 hours near the equator to 20+ in far northern summers.
Why fasting hours differ
The fast runs from Fajr (dawn) to Maghrib (sunset). Daylight length depends on latitude and season, so the closer a country is to the poles in summer, the longer the fast; the closer to the equator, the more constant it stays (around 12-13 hours year-round).
Longest and shortest fasts
In a northern-hemisphere summer Ramadan, cities like London or Oslo can fast 18-20+ hours, while equatorial cities stay near 12-13. As Ramadan shifts about 11 days earlier each year, every region eventually experiences both long and short fasts over time.
Fasting at extreme latitudes
Where day and night become extreme (or the sun barely sets), scholars advise following the timings of Makkah or the nearest city with a moderate, distinguishable day and night, so fasting stays humane and practicable.
