Santas' List Day is observed on December 04, 2017. It's the day that Santa makes his Naughty and Nice lists. Santa Claus has been believed to make a list of children throughout the world, categorizing them according to their behavior ("naughty" or "nice") and to deliver presents, including toys, and candy to all of the well-behaved children in the world, and sometimes coal to the naughty children, on the single night of Christmas Eve. He accomplishes this feat with the aid of the elves who make the toys in the workshop and the reindeer who pull his sleigh.
Santa Claus, also known as Saint Nicholas, Father Christmas, Kris Kringle and simply "Santa", is a figure with legendary, mythical, historical and folkloric origins who, in many western cultures, is said to bring gifts to the homes of the good children on the night before Christmas, December 24. However in some European countries children receive their presents on St. Nicholas' Day, December 6. (With material from: Wikipedia)
