The 12-hour clock is a timekeeping convention in which the 24 hours of the day are divided into two periods called ante meridiem (a.m., from Latin, literally "before midday") and post meridiem (p.m., "after midday"). Each period consists of 12 hours numbered 12 (acting as a zero), 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11. The a.m. period runs from midnight to noon, while the p.m. period runs from noon to midnight. The most common convention is to assign 12 a.m. to midnight and 12 p.m. to noon, defining both half days to have a closed (inclusive) beginning and open (exclusive) end. 12 noon and 12 midnight can more clearly and correctly express these times.

In timekeeping:
Ante Meridiem, in 12-hour clock notation, Latin for "before noon"
Anno Mundi, a Calendar era counting from the creation of the world
Anno Martyrum, used in the Coptic calendar
Post meridiem (also written P.M. and pm), Latin for "after noon". This is used to disambiguate hours of the day, in the 12-hour clock system

"a.m" stands for "ante-meridian"
and "p.m." stands for "post-meridian"..
these are tht latin equivalents for "before noon" and "after noon" respectively. So am and pm are ways used to differentiate the time of day before noon and after noon, and before midnight and after midnight as well.
