Since Santa's based on Odin...
But, Sinterklaas, St. Nicholas, Santa Claus, Father Christmas, All-Father, or whatever, it's all correct.
Fun fact, Santa has eight reindeer: Dasher, Dancer, Prancer, Vixen, Comet, Cupid, Donder, and Blitzen, representing the eight legs of Odin's flying horse, Sleipnir.
Another fun fact, a lot of our Western traditions of Christmas come from some Old Norse Yule traditions, and one of Odin's other names, of his long list of names is the Yule-Father, or, if you like, Father Christmas.
Aren't traditions fun?
