I grew up with a Betamax tape player under the family TV. It had a 24 hour clock and it was the timepiece in the house that was in the right spot to tell us all that it was bedtime. As a result I have an intuitive feel for the 24 hour clock. But if you haven’t used it regularly, which most ordinary Americans don’t, then yeah you just have to stop and do the arithmetic before you can connect 21:00 to your sense of time.
No, we just have to do a little kindergarten (age 5) math, the difference between 12 and 15 is 3.
The 3rd-grade math (age 8) of figuring what time it will be 9 hours and 47 minutes later is equally difficult whether using 24h or am/pm. And may be easier using angles on an analog clockface, especially for an old fart like me.
The real problem with time isn’t 12h vs 24h. It’s the increments 12/24/60/30/15/5 when the rest of our system is base 10.
Oh and Daylight Savings. Jet lag without getting to go anywhere. Fuck that shit.
If you see a two-digit number beginning with 1, drop the first number and subtract two from the second number. If your sum is negative, it’s that many hours before noon.
If your number begins with 2, do the same thing. If your number is negative, it’s that many hours before 10pm.
One time I was on shrooms in the PMs and it was really hard to figure out what the time was. The literal digits and the concept of time itself at some point.
Otherwise, never had an issue.
Also, is 24hour time not default on most phones? Or did I do that and forget about it at some point, and it’s only me, never paying attention to the time on other people’s phones
Nah, all you need is a little time to get used to it. It’s my default setting on most of my devices. Once you get used to it, it’s much easier to tell am vs pm at a glance, which is helpful when looking at timestamps (I work in IT, timestamps are important.)
I switched after being in a job where “meeting at 6” or “I’ll get in at 9” was 50/50 am or pm and I got sick of guessing and sometimes being 12 hours off.
No, it’s just associated with military time and those who don’t have friends from across the pond don’t necessarily know that other countries use that time format.
are Americans really confused with 15:30?

You know what fucks me up is that 21 has a “nine-ness” quality to it now that sometimes makes me mess up real math.
I think they see it as some kind of metric time, and therefore something to be avoided at all costs.
Yes, it angers and confuses them.

Pilot here, over been in the habit of using 12 hour for local time and 24 hour for zulu time. “12:45pm, 1745z”
Only inasmuch as I have to count from 12 because I don’t have the built-in instinct for that time format.
You’d get that instinct within at most a week though.

Anything to not subtract 12

I didn’t even know what that number says

I’m regularly looking at log timestamps and I still need a very brief half second to think about the time lol
Shouldn’t the system be storing timestamps in UTC anyway, and then displaying them in whatever localization settings you have?
I meant more for my personalized reading through logs. Some of our systems do log in UTC without correction, and they’re sometimes annoying.

Written as 1530, mostly only Americans who have been in the military and their friends will know what you mean.
15:30 they’ll know it’s a time.
And doctors, nurses, lab technicians, etc, plus anyone who can subtract twelve.
what is that, like extra noon or something?
No, it’s just associated with military time and those who don’t have friends from across the pond don’t necessarily know that other countries use that time format.
Just kidding we’re all just stupid
