To Rant, Or Not To Rant

A question about TMR

So, in the maze runner, do the gladers celebrate Christmas?
Do they even know about Christmas? And if they do how would it work?
Do they chop down a tree and doctorate it like we do?
And do they get presents?
How would that work?
Do they do a gift exchange or a secret Santa or something?
Or do they send letters down in the box asking what they want for Christmas?
Do they know about Santa clause?
Does Chuck believe in Santa clause?
Or, what if they celebrate Hanukah? What if they made up their own religion and they celebrated a holiday like Christmas or Hanukah?
These are important questions! I need to know if I'm supposed to wish the gladers a merry Christmas or a happy Hanukah or if I shouldn't wish them anything because they don't know about the holidays.

I'm sorry if this weird or confusing. Happy holidays everyone!
