Islam is the official religion in Morocco, but it exists in perfect co-existence with the other religions (freedom to practise other religions of revelation is guaranteed by the constitution). The day is marked by five calls to prayer. The muezzin announces them from the top of his minaret. During the month of Ramadan, the Moroccans fast, refraining from eating and smoking from sunrise to sunset. Obviously this disturbs daily life. Most Civil Service and public offices, monuments and shops alter their opening hours. However, non Muslims will always find something to eat in certain restaurants, particularly in hotels. The days may seem long, but the nights are wonderful!
