Birth Year Estimates and On-Screen Age Range

Producers placed the main timeline roughly between 1987 and 1995, meaning Jesse’s birth year is commonly estimated between 1969 and 1973, which aligns with a late twenties portrayal in later seasons and a mid teens to early twenties presence in earlier ones.
