Origin of a.m.
From the Latin word
ante merīdiem
usage note for a.m.
The abbreviation a.m. for Latin
ante meridiem, meaning “before noon,” refers to the period from midnight until noon. One minute before noon is 11:59 a.m. One minute after noon is 12:01 p.m. Many people distinguish between noon and midnight by saying
12 noon and
12 midnight. Expressions combining a.m. with morning (
6 a.m. in the morning ) and p.m. with
afternoon, evening, or
night (
9 p.m. at night ) are redundant and occur most often in casual speech and writing. Both
a.m. and
p.m. sometimes appear in capital letters, especially in printed matter.
