For a new AP (not a renewal), the key is when the pass was purchased. If you purchased a pass between Oct 1 and Jan 3, then it will be good for 13 months once activated. If you purchased any time after Jan 3, then it will be good for 12 months once activated. I purchased our passes online on Dec 27. We just activated them this past Saturday, Sept 2. They are good through Oct 2, 2018.
