While the calendar does say 201X, I think it's safe to say that the first human did not fall the same decade as the player. The exposition in New Home seems to imply that the first human fell many years before, given they came from a village and their consciousness had been trapped there for a very long time. Same could be said for the following six humans, with only the player being the most recent. The calendar is probably marked that year as a memento of sorts for Asgore, given he was their adoptive father.
