I do it because then I don’t put my calendar appointments in at oh, 3:00 AM.
15:00 is SOOOOOO much better for adhd me.
Also: it makes total sense! 24 hours, 24 separate numbers. It’s the most logical conclusion.
Also fewer wasted pixels on the am/pm text. 24h is just objectively superior in every way.
Large parts of the world use 24h time regularly. Only Americans, as far as I know, really struggle with 24h time, roundabouts, and bidets as concepts.
Bahh… The full day is 2π.
- 12:00 is π
- 15:00 is 3/2π And so on… Sane people use 2π = 𝜏 instead.
There are two comments here:
- I can count to 24
- I get confused by 12PM
The real crime is dividing the day into 24h, 60m per hour, 60s per min.
A LOT of western measurement was base 12, the only reason people are so used to base 10 is because that’s how many fingers most people have. Base 12 is really useful however, it is uniquely divisible and 60 as 5*12 is even more so.
are Americans really confused with 15:30?
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.
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.
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.
Anything to not subtract 12
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
I didn’t even know what that number says
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.)
Shouldn’t the system be storing timestamps in UTC anyway, and then displaying them in whatever localization settings you have?
I’m regularly looking at log timestamps and I still need a very brief half second to think about the time lol
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.
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
As someone who grew up with a 24-hour clock, I can deal with 12 hours. Usually there’s no confusion if your store opens at 7am or 7pm. But 12:30PM being a valid time and meaning ‘00:30 on the next day’ fucks me up every time.
12:30 AM is 00:30 though?
They shouldn’t even have 12 on the clock, it should be 0 because the 12 hour clock is modulo 12.
Case and point as to why it’s confusing lmao
“case in point” although "case and point " is arguably an eggcorn
12:30 pm is half-past noon.
12:30 am is half past midnight, or as you would say 00:30
The m is “meridian” which is noon (sun straight up)
The a is ante/before and the p is post/after
In olden days it was easier to look up and set your clock at noon than midnight.
By the definition of post meridian, though, half past noon should be 0:30 pm.
We use the 12 at both ends because there it is sitting at the top of the clock
12:30PM means 30 minutes after 12-noon.
Anyone saying that and meaning the middle of the night is just wrong, and if that’s a genuine thing people do it would drive me quite mad.
30 minutes after midnight is 12:30AM
Perfectly illustrates how it doesn’t make sense.
I can get behind
- 11.30pm
- 12.30pm
- 1.30am
Or
- 11.30pm
- 0.30am
- 1.30am
But
- 11.30pm
- 12.30am
- 1.30am
just doesn’t make sense.
You start counting the hours to the next noon at midnight, duh. That’s why it’s ante-meridian, and the beginning of a new day. If you want to go around calling it 00:30, most people would understand, even in America.
Did you mix up the first and third place? Because if 12:00 is “m”, it makes more sense for 12:30am to be night.

As I said, it always fucks me up. The AM/PM indicator wraps at a different hour than the hours. Aaargh!
Literally this. I was never in the military, and I’m glad they literally can’t draft me unless they lower a lot of requirements really fast. But 24-hour time is just so much more sensible. There’s no “AM or PM?” follow-up question, no guesswork. It just makes sense.
If they made metric time, I’d adopt that shit in a heartbeat.
the standard time that almost everyone uses is metric, i.e. is part of the metric system, its units are SI units. there was a system of decimal time, if that’s what you mean, developed in France during the revolution, where a day is 10 hours, each 100 minutes, each 100 seconds
so a decimal hour is 2.4 standard hours
a decimal minute is 1.44 standard minutes
a decimal second is 0.864 standard secondsI think it’s cheating to call it metric if it’s not decimal. Even some of the oldest analog clocks had 24-hour faces, they were just a bitch to read in a watch-size. You still have to do stupid math to figure out duration past the 12 or 24, and even with the 60 minutes/1 hour. Nothing metric or superior about it.
It doesn’t mean that.
This teaches you the value of terms like “half past noon“ and “quarter to midnight“
In Europe they say “point five past noon” and “point two five to midnight”
Is this a joke no one is getting or something?
is that what German humor is like?
In europe they say knock-knock-knock who’s there, not knock-knock whos there, for jokes.
Norwegian here. I don’t recognize this. Where in europe do they say it like that? We mostly use the 12 hour system to talk about time of day, but write in 24 hours. We don’t say am or pm though.
that seems overly complicated
“Closes at 25:00” is funny too
But luckily unambiguous.
12 hour time is a scam created by clockmakers who wanted to save paint.
Dealing with dates and times in software will get you formatting using year-month-date and 24 hour time as the least possible chance for confusion.
Date-Month-Year makes more sense to me
Higher chance for it to be interpreted as Month-Date-Year than Year-Month-Date though
fuck timezones. fuck timezones so god damned hard.
everything should be UTC. period.
also, f daylights crazing time!
My sleep schedule is shit. I set everything to 24 hours so that I don’t wake up at 8 PM and think that I’m late for my work at 8 AM.
24hr analog watches are the real shit, though!
Had a good emulated one on my phone homescreen for a long time, but unfortunately app is not supported by newer versions of Android any more… :-(
Wow, never knew that was a thing
Are you talking about a watch with 24 different numbers on it?
Are you talking about a watch with 24 different numbers on it?
Yes, arranged in a circle, 24 at the top, 12 at the bottom, lower part is day, upper part is night.
App also had a daylight indication shading depending on local sunrise/sunset.
Loved it!
I’ve been thinking for a while about getting a slow watch, a 24-hour watch that only has an hour hand
l like the idea, but I suspect it often might have the opposite effect as intended.
Imagine e.g. taking a quick glance at the watch to determine if you will still catch the bus - this would most likely result in you sprinting to the bus stop just to be on the safe side…
Someone can’t count past 12.
It’s cause crayons that come in 24 packs taste better than the 12 packs
And nurses I guess.
Well 24 is the highest number
When it was super critical I wake or not get paid while working in remote areas, you only have to set your alarm to the wrong am/pm once to change to 24 hour time
