A.M. and P.M. are abbreviations for ?ante meridiem? and ?post meridiem?. They mean ?before noon? and ?after noon? respectively. Noon is neither before or after noon; it is simply noon. Neither A.M. or P.M. are therefore correct. Midnight is both 12 hours before noon and 12 hours after noon. Therefore, either 12 A.M. or 12 P.M. could work as a designation for midnight, but both are ambiguous. (From NIST, ISO member). Craig
