1 January is holiday New Year. After a late morning start the main meal of the day is prepared which should include pork for good luck and lentils for prosperity in the new year. It's bad luck to eat fish, your luck could swim away or poultry, your luck could fly away. January 6 is the Feast of the Three Kings. In many Czech and Slovak villages, boys dress up as the three wise men “Kaspar, Balthazar and Melchior”. With a piece of chalk the boys write K + B + M (or K + M + B) above the doorways on houses, where people donate money for charity. This brings blessings on that home and its family for a year. The chalk letters should never be cleaned off, but only replaced the next year. This is also usually the day the Christmas tree is taken down.
