In Poland, Christmas traditions include sending Christmas cards to friends and family before Christmas, having a Christmas Eve supper with 12 dishes and an empty place set for guests, and sharing a wafer before the meal as a symbol of unity. On Christmas Eve, families decorate their Christmas trees with ornaments and lights and sing Christmas carols, and children anticipate presents from Father Christmas on December 6th and Christmas Eve under the tree. The most important tradition is attending Christmas Midnight Mass with family from December 24th to 25th.
