The Ramadan fast runs from Fajr — true dawn — until Maghrib at sunset, so its length each day is simply the gap between those two solar events. That gap depends overwhelmingly on two things: how far you live from the equator, and which season Ramadan currently occupies. Because the Islamic calendar is lunar, Ramadan arrives about eleven days earlier each year, completing a slow lap of all four seasons roughly every 33 years — and taking its fasting hours on the journey with it.

Near the equator the month is remarkably steady: Jakarta, Nairobi, or Singapore see dawn-to-sunset spans of about 13 hours whether Ramadan falls in June or December, because tropical day length barely changes. The drama begins at higher latitudes. When Ramadan coincides with northern summer, fasts in London have stretched past 18 hours and in Stockholm or Reykjavik toward 20 or more, with only a short night for eating, prayer, and sleep. The same summer Ramadan is gentle south of the equator — Cape Town, Sydney, and Santiago then sit in winter, fasting a comparatively mild 11 to 13 hours.
The coming years favor the northern hemisphere: Ramadan beginning in February 2027 means late-winter fasts of moderate length across Europe, North America, and the Middle East, shortening year by year until the cycle carries the month back toward the long days of northern summer in the 2040s.
Extreme latitudes pose a genuine question: above the Arctic Circle, midsummer brings days when the sun never sets and true dawn never occurs, making a literal dawn-to-sunset fast impossible. Islamic scholars have offered practical rulings — communities may follow the timetable of Makkah, or of the nearest city with a distinguishable day and night — and mosques in northern Norway, Alaska, and Finland publish schedules on exactly these principles.
Whatever the latitude, the daily anchors remain the same two solar moments. The prayer and sun times panel at ellatime.com computes today’s Fajr and Maghrib astronomically for any of 300+ cities, which during Ramadan is simply the fasting timetable by another name — though for beginning and ending the fast in congregation, the local mosque’s announced times remain the authority.
The hours also reshape the month’s daily architecture. In a long-fast summer, suhoor — the pre-dawn meal — creeps toward 2 or 3 AM in northern Europe, and the night compresses into a tight sequence of iftar, the Maghrib and Isha prayers, taraweeh at the mosque, a short sleep, and suhoor again; employers in Muslim-majority countries commonly shorten working hours to match. In a short-fast winter, the same rituals spread comfortably across long evenings, and the month feels — as older generations in the northern hemisphere remember from the 1990s — almost easy by comparison.
The 33-year lap also means every Muslim’s lifetime samples the full range: a child who first fasts an easy winter Ramadan will, as an adult, meet the same month in June, and later in winter again. Communities pass down season-specific customs accordingly — the dates and water of a quick winter iftar versus the elaborate hydration strategies of summer — a rotating tradition no fixed-season holiday ever develops.
