Meaning of Am PM?

Answer

AM means after midnight whereas PM means after midday. It is desirable to use 12 midnight and 12 noon where clarity is needed. To avoid ambiguity, railroads, airlines and insurance companies use 12:01 am for an event that begins during the day and 11:59pm for the ending of a day.
