ante meridiem and post meridiem

A.M. = ante meridiem
P.M. = post meridiem
They're from the Latin:
ante = before
post = after
meridiem = noon
The American Heritage Dictionary online says that:
"By definition, 12 a.m. denotes midnight, and 12 p.m. denotes noon, but there is sufficient confusion over these uses to make it
advisable to use 12 noon and 12 midnight where clarity is
required."

It is an abreviation for Ante Meridiem and Post Meridiem (Latin).
Latin Meaning: Ante Meridian "before midday or noon" & Post Meridian "after midday or noon".
