Observers have described Saudi Arabian society as deeply religious and deeply conservative.Saudi Arabia is the "only modern Muslim state to have been created by jihad, the only one to claim the Quran as its constitution", and the only Arab-Muslim country "to have escaped European imperialism." The many limitations on behaviour and dress are strictly enforced both legally and socially.
(Modest dress is compulsory for women in Islam but the color black for women and white for men is apparently based on tradition not religious scripture.) Saudi women also normally wear a full face veil, such as a niqāb.
During warm and hot weather, Saudi men and boys wear white thobes.
During the cool weather, wool thobes in dark colors are not uncommon.
Because Friday is the holiest day for Muslims, the weekend is Friday-Saturday.
In accordance with Wahhabi doctrine, only two religious holidays, Eid al-Fitr and Eid al-Adha, were publicly recognized, until 2006 when a non-religious holiday, the 23 September national holiday (which commemorates the unification of the kingdom) was reintroduced.
