They never states that they "fell"at the end of this year,just that they "came here"when you check the calander in New home,it possibly mean that chara came in NEW HOME at this time,not the underground.Plus i dont think that it's a coincidence that monsters moved on the same year as Chara fell,there's definetely a relation,especially if we note Chara's drawing of a golden flower that's even present in Toriel's house.
