A. Yes.
B. "366" days. If an AP is first-used on, say, Aug. 3, 2018, it will be good through close of business on Aug. 3, 2019.
C. Yes. It will be good for use through close of business on Nov. 22, 2018.
D. Nope. Nov. 22.
Why?
In your case, your AP will be good for an EXTRA day.
That is undoubtedly because when you bought your AP, it was back when the CM issuing the AP could MANUALLY INPUT
the anniversary (expiration) date by hand.
(And, a CM setting that date INACCURATELY was very, very common.)
However, within the last year, that situation has been remedied, as a new AP will NOW "start" when a guest
actually enters a park using that AP for the first time,
and the computer will then set the correct AP anniversary date, automatically.
