Notice I didn't put an exact date for when Monsterfest starts in the title. I'm not quite sure when it starts. The American Movie Classics site doesn't have an exact start date. If you click on Monsterfest Schedule it goes to October 21, and the first couple of movies are The Birds and Psycho, but then there are a few war movies and dramas, so I'm not sure if this is the "official" start of the Monsterfest but I'll take their own link as gospel.
