Most Serbians are Orthodox Christians who follow the Julian calendar. Thus, Christmas Eve is celebrated on Jan. 6 and Christmas on Jan. 7. In the old days, on Christmas Eve morning, Serbian fathers would take their eldest son to chop down (or in more recent times, buy) a young oak tree called a badnjak. There is a festive badnjak burning at night and then a meatless meal which varies from family to family. Typically, wheat grass, that was planted on St. Nicholas Day, symbolizing a good harvest, and cesnica, which isn't eaten until Christmas morning, are on the table.
