The imaginary line has to go somewhere. 🤷
I talked to a guy that thinks we should just all use Unix Epoch on here once. We’d still need local informal systems to describe the time of day and weekday, but the more I’ve thought about it the less stupid it sounds. Date/time systems are a pain in the ass and necessarily ugly.
What’s 12h/15h? How long a day is?
At 00:00 (midnight) UTC on monday, Russia’s time would be 12:00 (noon) of monday and alaska’s would be 15:00 (3 pm) of sunday.
Local time
What’s the h for?
Hour. Just a weird way to say 12:00 and 15:00 or 3pm and whatever 12:00 is in am/pm talk
12am is midnight and 12pm is noon. But most people just say “noon” or “midnight” because it’s less confusing.
That is confusing. “PM” is “post meridian” or, as I understand it, after the middle. One would think it wouldn’t be PM until 12:01 or at least 12:00:01.
Which is why I, as you said, use “noon” and “midnight.”
I can never remember it properly either but when someone reminds me (thanks samus12345) which way around it is it does kind of make sense.
If you think of 12:00 as literally an infinitesimal slice of time it’s not really possible to give it an am/pm distinction, as it is literally the devider between the two. BUT, in a more real-life approach 12:00 is probably not an infinitesimal slice of time but the minute after a digital clock flipped to 12:00. That can be 12:00:00.00004 or 12:00:30 or 12:00:59.999944. And all those are indisputably pm.
Couldn’t it be 00:00 PM? So zero time since meridian?
Correct - technically, noon is neither am nor pm, but clocks and the like have to have SOMETHING there, so am for midnight and pm for noon was arbitrarily chosen.
If you look at https://en.m.wikipedia.org/wiki/12-hour_clock#Confusion_at_noon_and_midnight it’s also not at all clear if 12:00 am is midnight or noon.
To me the clock jumping from 11:59 am to 12:00 pm and then again from 12:59 pm to 1:00 pm seems weird. Imho, stepping from 11:59 am to 12:00 am and from 12:59 am to 1:00 pm would be more logical.Didn’t expect this almost a month later.
I agree with probably 50% of your post. I agree that it’s not clear whether 12:00am is midnight or noon. However, if you recognize noon as the meridian, 12:00:01 is post meridian, i.e. after the middle (presuming that 12:00:00 was the meridian). It becomes after the middle immediately after the middle, not an hour later.
I don’t mean to be contrarian, but that’s not the part that confuses me personally. Really I think the world should just convert to 24 hour time.

Hour, it’s noon Monday on the Russian side and 3pm Sunday on the American side.
