Afghanistan has two main holidays, Eid al Fitr and Eid al Adha. Muslim holidays generally follow the lunar calendar, and for this reason, move each year relative to the calendar. The Islamic calendar has 12 months and approximately 354-355 days.

Ramadan is the month in which Muslims must fast from sun-up to sun-down. This is meant to feel how the poor people are without food or water. In addition, Muslims close their bodies off from earthly demands by denying themselves food and drink. This in turn allows for the nourishment of the soul.

Fasting is more than just the mere denial of food and drink. Muslims must also abstain from smoking and sexual contact. In addition, there are culture-specific beliefs regarding the watching of television, listening to music, and the perusal of anything that does not in some way enhance spirituality.
