The underlying observation is that the entire hour from X:00 - X:59 is either AM or PM, and not a mixture.
12:00 and 12:01 are both in the 12:XX hour, but 11:59 and 12:00 are not. Of course the whole thing is arbitrary, but the convention is that the 12:00 - 12:59 hour is PM, rather than just 12:00.
