Particular traditions and superstitious customs observed in Poland are not found elsewhere in Europe. Though Christmas Eve (''Wigilia'') is not a public holiday, it remains the most memorable day of the entire year. Trees are decorated on 24 December, hay is placed under the tablecloth to resemble Jesus' manger, Christmas wafers (''opłatek'') are shared between gathered guests and a twelve-dish meatless supper is served that same evening when the first star appears. An empty plate and seat are symbolically left at the table for an unexpected guest. On occasion, carolers journey around smaller towns with a folk Turoń creature until the Lent period.
