okay so i am making a timeline and since Equestria does not have a dating system i will list some events and if you have something you want to add just tell me what 2 events it comes between (From the list or other ponies' posts) Time of The 3 Tribes Rule of Discord Rule of The 2 Sisters Rule of Celestia Season 1 Season 2 Season 3 Equestria Girls Season 4 Rainbow rocks
80's Cheerilee says there is a dating system. Also, keep in mind that the first three seasons of the show all take place within a single year and the events depicted in them are most likely not all in chronological order. A proper timeline would end up being quite a bit more complex. It also lacks Sombra's rule over the Crystal Empire.
I just remembered this, basically is a video of the s1 episodes' timeline. I hope it helps you. Yet is only S1 remember.
