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.
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.
