RAMADAN – This holy holiday takes place in each year based upon the lunar calendar An ancient Islamic holiday whereby Muslims fast during daylight hours for thirty days.

Ramadan, considered as the most important holiday in Islam, happens on the ninth month of the twelve month lunar calendar followed in Islam. These lunar months are twelve days shorter than the Gregorian calendar, so Ramadan occurs earlier in each Gregorian year.

During the year of 2008, Ramadan in Morocco, Mauritania and Iran started a day later than in other countries celebrating Ramadan because the crescent of the new moon was not made visible.
