Ramadan, the Muslim holy month, is now in its second week. According to where you are, the pre-sunrise to sunset fast might last anywhere from 10 to 19 hours.

Every year, Ramadan begins 10 to 12 days early. This is due to the fact that the Islamic calendar is based on the lunar Hijri calendar, which has months lasting 29–30 days. In 2030, Ramadan will be observed twice, the first time on January 6 and the second time on December 27, because the lunar year is 11 days shorter than the solar year. Approximately 33 years from today, or in the year 2055, Ramadan will begin again.

Different countries have different lengths of daylight. In nations like Chile and New Zealand, Muslims fast an average of 11 to 12 hours, while those in northern countries like Iceland and Greenland fast for more than 17 hours on the first day of Ramadan.

This year, the number of fasting hours for Muslims in the Northern Hemisphere will be a bit shorter, and this trend will continue until 2031, when Ramadan will fall on the winter solstice, the shortest day of the year. After that, the number of hours of fasting will rise until the summer solstice, the northern hemisphere’s lengthiest day. The polar reverse will be true for Muslims residing south of the equator.
During the months of April through August, when the sun does not set in the far north, cities like Longyearbyen, Norway, are required by Islamic law to observe the sunset and sunrise times observed in Mecca, Saudi Arabia, or the nearest Muslim country.
