The American Heritage Dictionary of the English Language states "By convention, 12 AM denotes midnight and 12 PM denotes noon. Because of the potential for confusion, it is advisable to use 12 noon and 12 midnight."
or
Is noon 12 am or 12 pm?
To avoid confusion, the correct way to express 12 o'clock is 12 noon or 12 midnight.
Alternatively, the 24-hour clock system may be used - 12:00 and 24:00 (or 00:00) respectively.
The abbreviation am stands for ante-meridiem (before the Sun has crossed the meridian line) and pm stands for post-meridiem (after the Sun has crossed the meridian line).
At 12 noon, the Sun is at its highest point in the sky and directly over the meridian. It is therefore neither 'ante' (am) nor 'post' (pm).
