Home / Ramadan Zone / Fasting Hours Calculator
Ask a room of Muslims how long the fast is and you will get answers ranging from 'about twelve hours' to a theatrical groan — both roughly honest. This calculator replaces the guesswork with arithmetic: choose any of the 144 cities and any of the 30 days of Ramadan 2027, and it subtracts that day's Fajr from that day's Maghrib to give you the fast's true length, to the minute.
Fasting length is simply the distance between dawn and sunset, so it is governed by geography and season, not by the calendar alone. Ramadan 1448 falls in February and March 2027 — late winter in the northern hemisphere, late summer in the southern — which keeps most fasts moderate by historical standards, but the spread between cities is still real and, for travellers, worth knowing before you land.
Below the calculator, a comparison table lines up a spread of world cities for the same day you selected, longest first, and a callout names the longest and shortest fasts across all 144 cities for that day — computed live from the stored timetables, not copied from a listicle.
Two things set the length of a fast: latitude and the time of year. Near the equator, dawn and sunset barely move all year, so a city like Kuala Lumpur fasts roughly thirteen hours in almost every Ramadan. Further from the equator, days stretch and shrink with the seasons: a February Ramadan gives northern cities short, merciful fasts and southern-hemisphere cities their longer summer ones.
Ramadan drifts about eleven days earlier each year, cycling through all the seasons over roughly three decades. The Ramadan of 2016, in June, pushed some northern fasts past eighteen hours; the Ramadan of 2027, in February, asks far less. The calculator lets you watch this year's gentler geometry day by day, as the fast lengthens by a minute or so daily in most northern cities.
The duration shown counts from Fajr — the end of sehri — to Maghrib, when iftar begins. It does not count the night hours on either side, and it says nothing about difficulty: a thirteen-hour fast in cool February weather with a desk job is a different experience from twelve hours of outdoor labour in heat. Heat, work, health and habit all mediate what the raw number cannot.
One more honest note: the figure comes from calculated timetables, which carry a tolerance of about a minute at either end. For the length of a fast that is nothing; for the precise moment to stop eating, follow your local mosque's announced times.
The preset table exists for the conversation every multinational family has in the first week: who has it longest this year? Pick a day, and the table re-sorts itself. It is also genuinely useful — a student flying home mid-Ramadan, a family timing a visit to elderly parents, or a manager scheduling shifts for staff fasting in two different countries can all read the change in the fast's length before it surprises anyone.
The extremes callout underneath goes further, scanning every one of the 144 stored cities for the day you picked. In February 2027 the shortest fasts cluster in the far southern cities and the longest in the southern-hemisphere summer or the far north — check the callout for the day that matters to you rather than trusting anyone's summary, including ours.
In extreme latitudes there are places where dawn or sunset behave so unusually that scholars have discussed following the times of the nearest moderate region or of Makkah. None of the 144 cities on this site presents that problem in February 2027 — every city has a real Fajr and a real Maghrib every day — so the durations you see are straightforward subtractions that any local calendar will confirm.
It is that day's Maghrib minus that day's Fajr in the chosen city — the hours and minutes between the end of sehri and iftar — taken directly from the city's stored Ramadan 2027 timetable.
It changes day by day, which is why the extremes on this page are computed live from all 144 cities for the day you select rather than printed as a fixed claim. In February 2027 the longest fasts are generally in southern-hemisphere cities in their late summer.
Latitude. Even within one country, a northern city and a southern city can differ by twenty minutes or more, because dawn and sunset times shift with distance from the equator. Always use your own city's timetable, not the capital's.
Yes. In the northern hemisphere in February and March, days lengthen, so most fasts grow by roughly a minute a day — up to about half an hour across the month. Near the equator the change is only a few minutes in total.
The majority practice is to fast by the times of where you are: end sehri at your location's Fajr and break fast at its Maghrib. This calculator makes checking your destination's hours before you travel easy.
