How long will I fast? Ramadan 2072

Why fasting length changes from city to city

The fast runs from Fajr (dawn) to Maghrib (sunset). Its length depends on two things: the city's latitude and the time of year Ramadan falls in. The farther from the equator, the longer the days in summer and the shorter in winter. Because Ramadan moves about eleven days earlier each year, the fasting length for a given city shifts from one year to the next — which is why it's worth checking the figures for 2072.

How these durations are calculated

For each day we compute the Fajr and Maghrib times locally, with the same formulas as the prayer calendar, then measure the gap between them. No data is sent anywhere: everything runs in your browser. The calculation method (Fajr angle) is applied identically to every city compared, so the difference shown reflects geography rather than a mere choice of method.

Handling long fasting days well

When the fast is long, the two meals matter most: Suhur (before dawn) and Iftar (breaking the fast). Hydrate steadily between them, favour slow carbohydrates and fibre at Suhur, and avoid intense effort in the late afternoon. This matters especially for northern cities, where the range between the first and last day can exceed an hour.
