My first point that gumball is 13 is that he is now in 8th grade. The rerun depicts his first day of 8th grade, it can't be 7th because he was in that grade before. In the grades, when we see gumballs test, it says "8th grade" in the top right corner. In the end, penny states she is 12 when shes in her shell. In the ex, we see a scene of penny's birthdaym Since she was twelve before, and her shell id gone In the scene, she must be turning 13, and since gumball is the same age as penny, so must he. Then, in teh oracle, we see that the date is somewhere around october 20. Then in the grade, on gumballs test, we see it is october 4. Since the rerun depicted gumballs first day of 8th grade, and the grade takes place after that, we know the grade can't take place before the oracle, meaning a year has passed and gumbal has turned 13. That is why gumball is 13.
