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
Yeah. Which is what I said. 11:59:59.9999999 is indeed AM, jos like you said. 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.
Have you noticed how common it is for buses and trains to leave at 23:59? The idea is to make it clear what evening the train is really running.
In Finnish we call noon “12 o’clock” and midnight “0 o’clock”. Makes things a lot more clear.
And the first hour of a calendar day is indeed 0:00 until 0:59:59.99… Since there are only 24 hours in a day, there cannot be a “24:30”. (Except in internal timetables of bus companies, that typically run until 30 o’clock, as it still officially counts as the same working day)
So you call them 2 different things. Good.
Now imagine doing the same for all the other numbers in between.
That is what I get by “speaking 24 hours”.
And it takes less sillables.
What is the logic for distinguishing 12AM vs 12PM? Also, you have double of every element and need 2 more sillables each to distinguish.
It’s confusing and inefficient.
Get rid of Daylight Savings Time first, then we’ll talk about 24 hour time.
I use 24 hour time all the time in my job, I also have to use the time zone. I’m good with converting right now.
Daylight savings… yeah burn the and a hex on those who implemented it.
Wartime. Don’t know why the hell they didn’t remove it.
Right, that’s another one.
Everything after midday is PM. 12:00:00.00000001 is after midday. Therefore it can only be PM.
That’s the logic I use :)

You could just as well say the opposite.
Why?
Everything before midday is AM, etc. etc.

Sorry, I answered without giving enough thought. You are right in your reasoning of course.
Still, I find it confusing to have 2 completely different moments of the day represented by the same number.
In phrases like “After 12 PM on Monday”, “Before 12 AM” etc. I always need to think an extra second.
Another example is setting automatic responder on the mail, where I need to rely on 11:59, because the date is selected before the time of day.

Japan has something to say about that: 30-hour day time — clock doesn’t wrap if it’s a continuation of a previous day
