Unfortunately, Serbia is not a vegetarian - friendly country. Most of the people in Serbia are heavy meat - eaters. Do not take for granted that every restaurant has vegetarian cuisine, and do not try to find organic food shops.
The main Church of Serbia and Montenegro is the Orthodox Church. Like Russia, the tradition is to use the Julian calendar as opposed to the modern Gregorian calendar - at least when it comes to holidays and traditions. Day to day life is ruled by the Gregorian calendar.
The politics of Serbia function within the framework of a parliamentary republic.
