Noon is the time between AM and PM, midnight is the time between PM and AM. Check your auto insurance policy and get an effective date/time... it will
usually say 11:59 PM or 12:01 AM... They aren't about to be fooled.
The abbreviations "a.m." and "p.m." stand for "ante meridiem" and "post meridiem," which mean "before noon" and "after noon,"
respectively. Since noon is neither before noon nor after noon, a designation of either a.m. or p.m. is incorrect. Also, midnight is both twelve hours
before noon and twelve hours after noon.
Since the Latin word meridies means noon or midday, it is illogical to refer to noon as either "12 a.m." ("12 ante meridiem", or "12 o'clock
before noon") or as "12 p.m." ("12 post meridiem", or "12 o'clock after noon"). On the other hand, midnight could logically be called either
"12 p.m." (12 post meridiem, 12 hours after the previous noon) or "12 a.m." (12 ante meridiem, 12 hours before the following noon).
The correct designation for twelve o'clock is 12 noon or 12 midnight. As mentioned before, the abbreviation a.m. stands for ante meridiem (before the
Sun has crossed the line) and p.m. for post meridiem (after the Sun has crossed the line). At 12 noon the Sun is at its highest point in the sky and
directly over the meridian. It is therefore neither "ante" nor "post".
