Day of the Three Kings. Santa Claus or if you prefer Spanglish, "Santi Clo" was a minor player in the Christmas drama and he brought us some candy or a token to mark the beginning of the REAL 12 Days of Christmas from December 25th through January 5th. And while we don't hold fast to the tradition of the 3 Kings bringing the presents, we still keep our tree up at least through today.
