Post Apocalypse
23 October 2008I got a note the other day referring to 12:00p.m
when its author plainly meant noon.
Okay, now, folks, p.m.
stands for post meridiem
— after noon. Noon isn't after itself. There is a 12:01 p.m., a 12:00:01 p.m., a 12:00:00.0…01 p.m.. But if there is any 12:00 p.m., then it would be mid-night; which, awkwardly, is also the only candidate for 12:00 a.m., since noon also isn't before noon (ante meridiem) either.
Calling noon 12:00 m.
would just confuse people, as they'd take the m.
as standing for midnight
, but 12:00 n.
is nicely unambiguous.
