Yup don't forget the 100's of other religious and non-religious celebrations that have occurred in this hemisphere at around the same time and some of which are (much) older than your celebrations ; Amaterasu, Yule, Goru, Dazh Boh, Wayeb, Wren Day, Saturnalia,... your Christmas celebrations are actually thought to be adapted from some of those and a good deal from Ziemassvetki during the middle ages. oh yeah I forgot you're unique and it's all about you.
