I think there aren't many people who don't dig Christmas (in Christian world) and it seems that this festival is celebrated in the same way, but appearances can be deceptive. I'm going to tell about some Christmas traditions.
In Spain, Santa Claus doesn't bright the present, but the Three Wise Men on January (6th of January). In this country is quite celebrated Christmas lottery (22 of December) and the main award is called gordo (fat). During the Christmas Eve, the Spanish eat turkey (pavo relleno), shellfishes and a large number of sweets, like turrón. It's common knowledge that the world Spanish-speaking is quite diversified, I can quote a Costa Rican tradition which consists in visit a theme park and play darts and "raise the roof" on toboggans or carousels.
In he Netherlands there is one tradition which I find interesting and it´s connected with Spain: Santa Claus arrives in Holland in the night of 5 of December and coming back carries evil children.
There are many customs in common, like eat some sweets, but I've observed that more important is spend time with our relatives that stoke up at the table and c more and more people are getting out, they still spend time with other: at home, in cabin or on the beach in some tropical country.
