12 AM is midnight, 12 PM is midday.  I don't see the problem (though I'm
more in favour of 24-hour clocks for any important use).

Based on the fact that 12:00:01 AM is definitely in the morning, so
12:00:00 is held to be the dividing line, and the same for PM.

You could argue the other way, of course, but it's the convention.
