Cities With the Longest Fasting Hours Today
Oulu has the longest daily fast of any major city right now, running about 22h 09m from dawn to sunset.
Why Are the Fasting Hours So Long in These Cities?
The length of the Islamic fast, from Fajr at dawn to Maghrib at sunset, depends on latitude and the time of year. In the summer half of the year the cities with the longest fasts sit far from the equator, where the Sun rises early and sets late and dawn and dusk stretch long. The figures here are computed daily for each city's latitude and longitude.
This makes Ramadan very different around the world: a fast can last well over 18 hours in the far north during a northern-summer Ramadan, yet stay close to 12 hours near the equator all year. Today the longest fasting window among major cities is in Oulu, at about 22h 09m.
Frequently Asked Questions: Cities With the Longest Fasting Hours Today
Which city has the longest fast today?
Oulu currently has the longest daily fast among major cities, about 22h 09m from Fajr to Maghrib (as of July 15, 2026).
Why are fasting hours so much longer in some cities?
Because the gap between dawn and sunset grows with latitude. In summer, cities far from the equator have very long days, so the dawn-to-sunset fast is much longer there than near the equator.
How are fasting hours calculated?
The fast runs from Fajr (dawn) to Maghrib (sunset). We compute both times from each city's latitude and longitude for the current date using a standard calculation method, then take the difference.
