You know about 201X, right? My theory is that it's basically 2010. Why? Because X stands for 10 in roman numerals, and if you decipher 201X, it's basically 2010.

More evidence is that when you finish the game, in the True Pacifist Ending, there are modern inventions like 2016. So, when Frisk fell down, I think it was 2016, and when Chara fell down, it was 2010. (201X)
