Right, and the AA RTW desk was happy to have the last flight depart per that guideline (that is, one day before the first flight the previous calendar year) but AA ticketing insisted it be moved one day before that. That's why I said one day before the one-year mark.

Well, I find the term vague because a "month" means different things in different contexts. It's often used as a standardized 30-day interval, other times a calendar month (which might be 28, 29, 30, or 31 days).

Yes, "365 days" is clear and not ambiguous, except when a leap year comes into play. If my first flight is, say, February 28, 2016 (a leap year that has February 29), can my last flight be February 27 of the following year, or must it be February 26?
