I think that Season Four is the exception.

It's specifically stated that the first episode takes place on Samhain, and the finale two-parter starts with the Beltane feast for exactly six months (or eighteen, though it seems highly unlikely) plus the time it took for Morgana to conquer Camelot and be ousted.
