In Poland, Christmas Eve is the most solemn evening of the year with rich liturgies. Traditionally, families break opłatek wafers and share a meal when the first star appears in the sky, leaving an empty space at the table to remember absent loved ones. After supper, people sing carols and participate in customs that vary by region, such as pulling the tablecloth from under a straw or giving leftovers to animals believed to speak at midnight. Midnight Mass commemorates the shepherds' visit to Bethlehem.
