Christmas Eve in Poland is marked by an important family dinner that traditionally includes 12 meat-free dishes. Families share opłatek wafers and leave hay under the tablecloth to commemorate Jesus' birth. After midnight mass, some families enjoy a second dinner with meat. On Christmas Day and its eve, people attend church, exchange gifts, sing carols and feast with family and friends, often including meat-based dishes like hunter's stew. Nativity scenes in churches are also an important Christmas tradition in Poland.
