Please explain why in the French phrase “Les vendredis soir”, "soir’ is an adverb?, which for reasons I don’t understand “les vendredis soirs” is incorrect but “les vendredis soir” is.

I would guess there’s an implied contraction “les vendredis [au] soir”. I would assume that, depending on context, the whole thing counts as an adverbial phrase, the verb being whatever happens on those Friday evenings
