Belgrade is the capital of the Republic of Serbia and the largest and most populous city in the territory of the former Yugoslavia.
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.
Serbia religions include the Serbian Orthodox Church, the Muslim Community of Serbia that is mostly Sunni, the Jews, the Native minority following regional faith, and the Eastern Orthodox church.
