Also keep in mind that Chara's arrival at New Home at The End of 201X is a power hidden bit of lore that's difficult to find.

To get it, you need to both finish a neutral/pacifist run of the game to learn that Asgore's calendar has a date at The End of 201X circled.

Then you have to complete a No Mercy Run, so that Narrator Chara then tells you that this mysterious date is the date Chara arrived at New Home.

You need to remember these details spread far apart, combine them, then plug it into the rest of the lore to see what you get.

This was done super-deliberately. There's no way that this date doesn't have a special lore significance.

And I've pointed out what I think it means.
