This is one of the pettiest things I've ever heard.
12 months is still a year, no matter what month it begins from.
How is the season 12 months. If the season was twelve months long, it would go on continuously from now until the rapture. The season is 9-10 months long, and anyone who refers to this as a year is a foolish person. The name should be changed.
Since when has year and season not been interchangeable? It's so petty, obviously they're different, but everyone knows what they're talking about.
