Switch holiday exploit?

if you don’t exit the game on the switch i think it doesn’t update the date in-game? On the 23rd or so i could still trick or treat because i hadn’t exited my game and i’m pretty sure it was supposed to end after two weeks? (I tried double-checking but can only find info from last year so far as I can tell). I since did exit the app but haven’t got back to it yet to see if that ended it.
