St. Nicholas Day - December 6th On the Eve of St Nicholas Day, it is a custom in some countries for children to leave straw and carrots in their shoes for St Nicholas' horse. St Nicholas (or Sinterklaas) comes to their house while they are sleeping, and if they've been good, he leaves candy and treats in place of the straw. If they have been bad, St. Nicholas leaves a switch. Have you been good this year? You've been good, so you get treats! Happy St. Nicholas Day!
