Answer 3

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.
This expression was not used in the English language until 1762.
Although the abbreviation of "p.m.", which is Latin for 'post meridiem' or "after noon" was used as early as1647.

"meridiem" refers to the Prime Meridian, that is designated zero degree (0°) longitude, from which all other longitudes are measured. By international convention, it passes through the original site of the Royal Observatory in Greenwich, England; for this reason, it is sometimes called the Greenwich meridian. Universal time, the standard basis for determining time throughout the world, is civil time measured at the prime meridian.

The Greenwich Meridian established by Sir George Airy in 1851 was agreed upon as the international standard in October 1884. At the behest of U.S. President Chester A. Arthur, 41 delegates from 25 nations met in Washington, D.C., USA, for the International Meridian Conference.
