I made a timeline of the Animal Crossing world
So I created a theoretical timeline of the version of Earth that Animal Crossing takes place on that I have attached to this post. I get pretty deep into the specifics of it and how it works so it's pretty long.
I know I made a version of this post around a couple of weeks ago but I decided to remove that post as I wasn't happy with that version of the timeline in hindsight, due to multiple grammatical errors and not being happy with some of my reasoning for when events happened, particularly my choice and reasons for Tom Nook's birth year (which bled into the when the Able Sisters' life events occurred), which has been heavily reworked and said year has also been changed.
I also improved my explanations of certain important details. amiibo Festival was also missing from the timeline before. Further tweaks may be made in future. Feel free to give me feedback or details that I may have missed. I would appreciate if you gave the timeline a read as it has been improved a lot since I posted it here before, and I have worked very hard on it XD.
Special thanks to Youtube user Prizm95 whose Mario Timeline videos inspired me to make this project: https://www.youtube.com/watch?v=YbOBaFZ4Ta8&t=4963s
