What is the Full Form of A.M. and P.M.

A.M. and P.M.

What is Noon and Midnight?

A.M. and P.M. start immediately after Midnight and Noon (Midday) respectively.

This means that 00:00 A.M. or 00:00 P.M. (or 12:00 A.M. and 12:00 P.M.) have no meaning.

Every day starts precisely at midnight and A.M. starts immediately after that point in time e.g. 00:00:01 A.M.

To avoid confusion timetables, when scheduling around midnight, prefer to use either 23:59 or 00:01 to avoid confusion as to which day is being referred to.

It is after Noon that P.M. starts e.g. 00:00:01 PM (12:00:01).
