Ramadan

The month of Ramadan started yesterday which is the period of fasting for Muslims. During the daylight hours they deny themselves food and drink, including water. They are allowed a small meal before daybreak and after sunset but over indulgence in order to compensate for the lack of sustenance during the day isn't considered entering the spirit of Ramadan.

Ramadan is on the ninth month of the Islamic calendar which is based on the phases of the moon, so some times the days will be shorter and I guess fasting slightly easier. With longer daylight as we have currently, I would have thought that fasting will be even more difficult so spare a thought for your Islamic colleagues.
