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.
In Romania, Christmas and mid-winter celebrations last from 20th December to 7th January. The 20th is when people in Romania celebrate St. Ignatius's Day. It is traditional that if the family keep pigs, one is killed on this day. The meat from the pig is used in the Christmas meals.
In France, children leave their shoes by the fireplace on the Christmas Eve so that Pere Noel can fill them with gifts and in the Christmas morning, they usually find sweets, fruits, nuts and small toys for them hung on the tree. Puppets and plays are conducted in cathedral squares to re-enact Nativity plays.
