Fasting Hours Calculator 2027
Fasting Hours Calculator
How long every fast of Ramadan 2027 lasts where you live.
How long will you fast?
The length of a fast is the time from Fajr to Maghrib, which changes with latitude and the season. In February and March 2027 the northern hemisphere is moving into spring, so fasts lengthen slightly day by day in the north and shorten in the south.
How to use it
- Set your location.
- The three boxes show the shortest, longest and average fast of the month.
- The bar chart shows every displayed day; hover or tap a bar for its date and calculated fasting duration.
Extreme latitudes
Above roughly 48° north or south, twilight can be continuous. In those regions many scholars advise following the timings of the nearest moderate city or of Makkah; ask your local scholars which ruling to apply.

How fasting duration is measured
The displayed duration is the interval from calculated Fajr to calculated Maghrib for each date. It therefore changes with latitude, season, method and time-zone rules. The shortest, longest and average values are calculated from valid daily results only.
Why the line changes over the month
Day length changes gradually as the Earth moves through the season. In February and March 2027, the direction and size of that change depend on hemisphere and latitude. The chart therefore uses actual daily calculations rather than applying one fixed fasting duration to the whole month.
Invalid solar events
Days without a normal Fajr/Maghrib pair are excluded from the average rather than converted into a misleading duration.
Frequently asked questions
Which country has the longest fast in 2027?
Places furthest from the equator in the southern hemisphere in February–March, such as southern Chile and New Zealand, have the longest daylight fasts; equatorial countries stay near 12–13 hours.
Why does my fast get longer each day?
Day length increases toward the spring equinox in the northern hemisphere, so Maghrib moves later faster than Fajr moves later.
