ante meridiem (a.m., English: "before midday") and post meridiem (p.m., English: "after midday")

I think of it like this, what is 12:01 am closer to?
You don't need a poll as the answer is categorically 12am is midnight and 12pm is midday.
Anything else is simply wrong.
It's technically 12 noon. It would be 12.01PM
This is why the 24hr clock is superior.
Maybe so but 1200 hours is still 1200 so some buffoon will always ask "is that AM or PM?"
12PM = Dark, cloudy, raining
12AM = Darker, cloudier, more rain, moon can be visible sometimes.
Simples...unless you're in a country where you get midnight sun.
00:00 = Midnight
12:00 = Noon
&
23:58 = Iron Maiden! \/
