p.m. begins at noon and ends at midnight
(p.m. from Latin: post meridiem, after mid-day).
noon itself is neither a.m. nor p.m., the same way that 0 is neither positive nor negative.
Most people on the planet have solved the problem by calling noon: 12:00
and midnight: 0:00 (or 24:00 which is a less useful way).
By this convention, if you must use a.m. or p.m., then 0:00 must be a.m. (it is the start of the day, therefore it is before noon), which leaves p.m. for noon.
The few countries that still use the 12 hour clock need a device such as a.m. and p.m. to distinguish which '9 o-clock' is meant when asking someone to meet you at 9.
Most of them seem to use the convention described above (noon is 12 pm). This makes sense because 12:01 is definitely after noon (therefore p.m.). You would not want 12:00 a.m. to be immediately followed by 12:01 p.m.

When forced to make a choice, people will call 0 positive. Mathematicians include it in the 'non-negative' numbers (and, also, in the non-positive numbers). However, they will not say that 0 is strictly positive.

Confusingly (I think) pm starts at 12 noon when I believe it should start the moment after. After all the second leading up to 12:00 is an am (ante meridiem) moment and so the question arises is "the hour" what has just occurred or what is about to occur. I think the former but the convention is that midday is called 12:00pm in spite of the fact that the previous hour is 11:00am, of course if we were to call 12noon, 12:00am and 12:01pm it may be confusing. Perhaps 12:00pm midnight which can alternatively called 00:00hour particularly on the 24hour clock is a less confusing time to discuss your query.
