That's a very common misconception,monsters aren't celebrating Christmas.If you talk to residents,they inform that decorating a fir is based on Snowdin residents tradition:many children decorated Gyftrot in the past so residents gave them gifts to excuse their children's behaviour,and it became a tradition to decorate a fir (since Gyftrot have firs on their horns), put gifts under it and exchange them. Yes, but you don't have to actually be a Christian to use the A.D. year system. It's a common convention that most of the world uses for convience.

And whatever the monsters believe, they have a Winter Holiday program that involves decorating a tree, that's indistinguisable from a traditional Christmas Tree. This is a civilzation that's been exposed to the idea of Christmas before, and they've adopted their own version of the cultural holiday.

So are the monsters aware of the A.D. year system? Yes, absolutely. They likely used it before they were sealed. And updated it after they started to study human garbage, pouncing on a more reliable way to tell time.
