Merry Christmas, and my best wishes for you and your family!
If you notice the absence of a screenshot of my Star Wars: The Old Republic character in a Santa suit wielding a lightsaber, that is because SWTOR up to now does not have holiday events. And I think that is a good thing. As much as some people might like to hunt the Abominable Greench and unpack virtual presents under the tree in Orgrimmar in World of Warcraft at Christmas, it only makes the world less coherent and less believable. I really don't want the spectacle of watching Jedi search for Easter eggs in Coruscant, or participating in a virtual Oktoberfest.
I think it is better if SWTOR sticks to the Star Wars lore, and doesn't invent holiday events which happen to be similar to real world holidays on similar dates.
