Ramadan, the ninth month of the Islamic calendar, is considered holy by Muslims. It is observed by Muslims worldwide as a month of fasting (Sawm) to commemorate the first revelation of the Quran to Prophet Mohammed.
During this holy month, Muslims fast from dawn until sunset, refrain from consuming food, drinking liquids, smoking, and engaging in sexual relations.
This year, fasting hours ranges between 11 hours and 21 hours. However, on the average Muslims all over the world fast for about 15 hours per day.
Here are countries with the longest duration of fast this year:
Greenland (21 hours 2 minutes)
Iceland (21 hours)
Finland (19 hours 56 minutes)
Norway (19 hours 48 minutes).
Apart from long hours of fast, these countries along with Northwest Territories of Canada have perpetual daylight, with no demarcation between night and day, posing an additional challenge for those who fast.
