I only know about Christmas, from Misty, and Hanukkah, from the spirits.

[And maybe from their own past. Maybe.]

And Thanksgiving, but that was during the attacks. So no one did anything about it.

[The Soldier doesn't know why the spirits are celebrating it, either, but they're starting to think this is some kind of alternate Earth or something, given the calendar dates and the prevalence of humans in the world's past.]

If I find out about any other ones, I'll tell you, though.
