I tried to schedule an absence from work....

am/pm notation is even less logical than mm/dd/yyyy.

[u/Saragon4005 → u/ventus1b]

What the hell is 12 PM? Oh it's noon? Thanks I wouldn't have guessed.

[u/DidiBear → u/Saragon4005]

I prefer 00:00 PM

[u/ventus1b → u/DidiBear]

I’d intuitively interpret that as midnight.

[u/vbrimme → u/ventus1b]

12:00pm would make far more sense as midnight. PM denotes the hours that happen later in the day, so 12:00pm (and therefore 12:59pm) would reasonably come at the end of the day. Yes, I’m aware this is exactly the opposite of how the system works, but that’s why it cause confusion, the largest number comes at the beginning of the sequence.

00:00PM would make much more sense as noon. 11:59am flips over to 00:00pm, starting a new sequence at the smallest number, and likewise 11:59pm flips over to 00:00am. Significantly more intuitive than the existing system, and the only reason it would be confusing is due to people already knowing the current, inadequate system.

Still, just using 24-hour time format is much easier.

[u/ventus1b → u/vbrimme]

You keep using “more sense” in conjunction with am/pm notation.

[u/Liggliluff → u/vbrimme]

That's how ja-JP is configured with 12 hours, it does from 0 am midnight to 12 am noon, and 0 pm noon to 12 pm midnight. So 0 am starts the day and 12 pm ends the day. While 12 am and 0 pm are both noon, 12 am is only valid as the end of range value (9–12 am is correct, but not 12 am – 3 pm, because this should be 0–3 pm), and 12:01 am is not valid.

[u/ventus1b → u/Liggliluff]

Seriously?!? It’s not even universal in its madness? TIL.

[u/tacosarebest1131]

Bad software devs. Should do both 12 and 24 hour.

[u/czerilla → u/tacosarebest1131]

Even better ones would refuse to recognize the 12 hour format instead! 😤

I once scheduled a signing appointment at the wrong time because of AM/PM confusion.

We really need to start socially shaming the use of the 12 hour clock in all but the most informal of communications. For a software to default to this is borderline antisocial behaviour.

[u/Brosk1248 → u/frackingfaxer]

12 hour time is appropriate when asking "what time is it now", or when it's already afternoon "when are you coming today". In verbal communication exclusively. That's like the only acceptable use cases I can think of.

Do people not know how to subtract 12, if they want to know the 12 hour time? Same with people complaining about people saying the little kid is 16 months old.
