Ages reflect birthdays through today; upcoming December birthdays will tick up later this month.
Why ages differ from on-screen school years
The show’s timeline is anchored in the 1980s, so the characters’ “grade levels” don’t map to the actors’ real ages. Filming gaps and staggered release volumes also mean viewers sometimes meet a character “a year younger” than the performer playing them. That’s normal for long-running ensemble dramas—especially ones that started with a very young cast.
