In Germany, Christmas traditions vary by region. Till the reformation Saint Nicholas' Day, December 6, Saint Nicholas was the main provider of Christmas presents. Nikolaus still puts goodies in children's shoes on that day. Sometimes St. Nicholas visits children in kindergarten, schools or at public events. They have to recite a short poem or sing a song in order to get sweets or a small gift. "Knecht Ruprecht" (the servant Ruprecht) – dressed in dark clothes with devil-like traits (usually noted as a long, bright red tongue and with a stick or a small whip in the hand) – sometimes accompanies St. Nicholas. His duty is to punish those children who have not behaved during the year. Usually he merely stands near St. Nicholas as a warning to be good and polite. Nikolaus as well for some Glühwein for adults, there are some traditions connected with local firefighters, riders associations and church congregations.
