Talk:You're Getting Old/Trivia/@comment-29569222-20160810104922

I'm not sure if it would be considered a goof or a continuity error, but the entire episode implies that Stan is the first of the boys to hit ten. We know for sure when both Stan and Kyle's birthdays are from "You have 0 Friends", and I think Cartman and Kenny's birthdays are both marked on officially licensed South Park calendars. Given the way the school year works, the oldest boy should be Kenny (March 22), then Kyle (May 26), then Cartman (July 1), with Stan actually coming in as the youngest of the main four (Oct 19). His birthday would be the first to be hit every school year, but whatever age he turns, the others should turn a year older than him after New Years. If he is the oldest, the only way to explain it would be to say he was held back a year from school for some reason. Not to imply that South Park really sticks to a sense of continuity when it comes to the years passing, as the boys are only one grade higher than they started, but it does seem like a significant error to imply Stan turned ten first. Unless I'm missing something. I might be. I'd like to know.
