Boku no Hero Academia

[KrayZ33]

I don't know why you associate seasons with years or something like that.

If a fight or "situation" lasts for 5 episodes we have to wait 1-2 months, for the characters however, that took place in more or less 3 hours.

They are learning to be heroes and the show is about exactly that.

Like.. it's what the show is supposed to be about.
It's not about what happens after school ends and if they go to college or not.

From Deku being accepted to UA to the Overhaul arc - a timespan of ~6 months seems likely.

edit: doesn't the sign still say 1-A(?)
The cultural festival wasn't that long ago either (post Overhaul arc). That's usually in October or something.
