Regarding the “what year and decade are we leaving and entering” debate: Many places in the world count a person as 1 year old on the day of their birth. This is especially true in much of Asia. There is really nothing to argue about here because both sides are correct depending on where you are born and how the culture counts. This is fact and not mysterious information. No side is “righter” than the other. I am surprised it went unmentioned in the several articles that have recently appeared discussing the subject.
