Polish Christmas customs involve four weeks of Advent preparation. On Christmas Eve (Wigilia), families decorate trees with candles and paper, place gifts underneath, and prepare a special supper of 12 dishes including carp and pierogi. The meal begins after the first star appears. On Christmas Day, people celebrate with breakfast and meat before observing the weather signs. St. Stephen's Day on December 26 involves caroling from house to house. New Year's Eve celebrations vary from balls to family gatherings. The Epiphany on January 6 ends the Christmas season and involves blessing homes with the initials K+M+B.
