Many other varying cultural traditions and experiences are also associated with Christmas Eve around the world, including the gathering of family and friends, the singing of Christmas carols, the illumination and enjoyment of Christmas lights, trees, and other decorations, the wrapping, exchange and opening of gifts, and general preparation for Christmas Day. Legendary Christmas gift-bearing figures including Santa Claus, Father Christmas, Christkind, and Saint Nicholas are also often said to depart for their annual journey to deliver presents to children around the world on Christmas Eve, although until the Protestant introduction of Christkind in 16th-century Europe, such figures were said to instead deliver presents on the eve of Saint Nicholas' feast day (6 December).
