Ramadan Calendar

Estimate Ramadan dates and daily fasting times

This calendar finds the Ramadan that starts during a Gregorian year, then lists Suhoor and Iftar for each day in a city you choose. The month boundaries come from the tabular Islamic civil calendar, the arithmetic calendar used for planning when an official moon sighting has not been announced. Expect the first or last day to differ by a day or two from a local announcement.

How the dates and times are calculated

January 1 of the selected year is converted to a Hijri date. If that date is already in Ramadan or later, the Ramadan that starts in the selected Gregorian year belongs to the next Hijri year. Otherwise it belongs to the current Hijri year. Ramadan is the ninth Hijri month and is 30 days in this tabular cycle for the years this tool highlights by default.

Suhoor ends at Fajr and Iftar is Maghrib. Both come from standard solar calculations for the city's latitude and longitude. The Fajr angle changes how far the sun is below the horizon at dawn. 18 degrees matches a common Muslim World League setting. Changing the angle moves the Suhoor column and the fasting length. It does not move the calendar dates.
