Their birthdays

[FirePuppy 735]

I should know that nopony in the Mane Six has any known ages throughout the show, but it's noted that in a Season 1 episode, Fluttershy is roughly one year older than Pinkie Pie, which makes her about the same age as Rarity, which makes both of them the oldest two of the Mane Six, as all Mane Six look like they're around the same age.

 

And since Pinkie Pie celebrated her birthday before Twilight's, that could make Twilight the only one of the Mane Six slightly younger than Pinkie, by one or a few months, making her the youngest, since she's still a student, and Twilight's birthday took place only 10 episodes after Pinkie's.

 

Which leaves Applejack and Rainbow Dash the two in the middle. Between them, Rainbow Dash could be older than Applejack, as Applejack still lives with her family, and Rainbow Dash celebrated her birthday in Season 4, potentially making Dash now the same age as Fluttershy.

 

And that's my theory.

Nice theory, by the way!
