Comment on Whoever invented the 12-hour clock never doubted that people will always know if it's day or night

Everything after midday is PM. 12:00:00.00000001 is after midday. Therefore it can only be PM.

That’s the logic I use :)

Historically, the style manual of the United States Government Printing Office used 12 a.m. for noon and 12 p.m. for midnight, though this was reversed in its 2008 editions.

I also remember there were some countries that have 12 AM mean noon, but I may be mistaken as I can’t find a source

You could just as well say the opposite.

    Yeah. Which is what I said. 11:59:59.9999999 is indeed AM. And then comes a tiny sliver of time that is precisely at the border, but a trillionth of a picosecond after that, you’re in the PM world. After the infinitely short moment that is the actual precise noon.
