THE Islamic holy month of Ramadan begins at the sighting of the
new moon in the ninth month of the lunar calendar. During Ramadan
(which starts on July 9th this year) observant Muslims around the world abstain from food and drink between sunrise and sunset. Because it follows the lunar calendar, Ramadan shifts by 11 days a year
in relation to the Gregorian calendar. In some places, like Saudi
Arabia, that makes little difference to the number of hours a day
Muslims must fast. But what happens in northern countries where there
can be up to 24 hours of darkness or light, depending on the time of
year? What about in Antarctica, where periods of continuous daylight and
continuous darkness last several months? How do Muslims observe Ramadan
in places where the sun does not set?
