adverb

  1. 1

    In the 12-hour period from noon to midnight (the latter half of the day) when using the 12-hour clock.

    HOURLY PRECIPITATION … 9 PM THROUGH 12 PM (MIDNIGHT) ZERO DAILY TOTAL

    We never say 12 a.m. or 12 p.m. It's either 12 midnight or 12 noon, respectively.

    The 12-hour clock uses A.M. for the morning hours of midnight (12:00 A.M.) to almost noon (11:59 A.M.) and the P.M. designation for the hours from noon (12:00 P.M.) to almost midnight (11:59 PM).

    The 12-hour clock, which is used in the U.S., Canada, and a few other countries, divides time into two cycles: a.m. (ante meridiem, Latin for before midday) from midnight, 12 a.m., to 11:59 a.m.; and p.m. (post meridiem, Latin for after midday) from noon, 12 p.m., to 11:59 p.m.
