Question between downtown and ucchan-nanchan

Between Downtown and Uncchan-Nanchan which one is the senior? I’ve search the Wikipedia about them and it says that Downtown was formed in 1982 and Unchan-Nanchan in 1985.

Be sure to compare Unchan-Nanchan ages and downtown ages. They could formed in 1985, but Uchan-Nanchan can be older than Matsumoto and Hamada.

EDIT: Uncchan-Nanchan are younger than Downtown. Uncchan is a year younger while Nanchan is 2 years younger than Matsumoto and Hamada.

Comedians usually decide junior and senior based on the day they started comedy as a profession.
But either way seeems like uchan nanchan would be junior based on the info you guys found.

This, plus also how many years they are at the same company (if that’s the case).
