The territorial organization of Serbia is regulated by the Law on Territorial Organization, adopted by the National Assembly of Serbia on 29 December 2007. Under the Law, the units of the territorial organization are: municipalities, cities and autonomous provinces.
The Serbian climate varies between a continental climate in the north, with cold winters, and hot, humid summers with well distributed rainfall patterns, and a more Adriatic climate in the south with hot, dry summers and autumns and relatively cold winters with heavy inland snowfall.
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.
