Morocco is one of those religious frontiers where orthodoxy and local
custom have met and compromised. The veneration of saints is frowned on
by the orthodox Sunni Muslims but Islam, like Christianity, is made up
of many sects and such festivals continue. It's worth asking around for
details of festival dates because they follow the Islamic calendar,
which is lunar and alters a little every year.
Around May there's the Mousseum of Sidi Mohammed Ma al-Ainin,
an occasion to see the 'blue people' (Tuareg nomads of the Sahara) and
the commercial gathering of tribes. The National Folklore Festival of
Marrakesh is a 10-day tourist event attended by dancers, musicians
and other entertainers from around the country. In October, the little
Northern town of Erfoud hosts a festival in honor of the quintessential
desert fruit, the date. Independence Day, one of five national
secular holidays, is celebrated on 18 November.
