Current Events > 12hr clocks > 24hr clocks

(+) Yeah! (+)

I'd honestly like to hear some situations where people can mistake AM and PM.
Please give actual examples.

Flight times. Work schedules.

Okay here's one that really happened irl. We were working on a project. The leader said something like this before weekend, "Let's have a short video conference at 9.30 tomorrow to confirm the details." 'Short' usually meant 10-15 minutes so we didn't mind.

The following day we (except the leader) hold a conference at 9.30AM. The reason was simple, 9.30AM is a working hour and 9.30PM is a resting hour. Since the leader didn't show up, we cancelled the conference since we already knew the details anyway.

We found out much later that the leader showed up to an empty room at 9.30PM. That went real bad and later on we had an argument like this:
Team: 9.30AM because 9.30PM=sleep.
Leader: 9.30PM because it's weekend.

24 hour clock is objectively superior, anybody saying otherwise is wrong.

Military uses 24 hour clock for a reason. That reason being it leaves no room for ambiguity.

And then we have the regional problem if "half 8" means "half past 8" or "half towards 8".

Half 8 is 7:30.
Half over 8 is 8:30.

False. Here in Korea, majority of my cafe meet ups have been in the evening. Only like thrice in my near two years, have I been to a cafe with someone else in the morning. Did more morning meets in the states, but evening meets weren't uncommon either.

Half 8 is 7:30.
Half over 8 is 8:30.

"Meet me at 8" 8AM? 8PM? Which one?
Well, are you meeting for a concert or a day trip?
Meeting for the gym.
Is it a work day or the weekend?
I go to the gym with the bros same times every day.

umm just use 24hr clocks;)

I'm not used to a 24 hr clock, so why do I wanna do math to figure out the time?

My 8 year old can do it no problem, I'm sure you can handle it.

Did you read my previous post? I said verbal conversation and texting people.

1) nobody meets at 8pm to have coffee
2) even if they did, youd know based on the context (of which none was provided ITT)

Thing is, this conversation doesn't happen.

If you're dealing with someone who legit can't figure out whether to show up when the sun is up or down, that conversation is worst case going to go

Leader said, "Let's meet at 9.30 tomorrow." No AM/PM mentioned or asked because everyone thought it was clear.

Sometimes later
Team: "It's 9.30 AM because it's job meeting and 9.30 AM is working hour."
Leader: "It's 9.30 PM because it's weekend."

16 o clock sounds dumb af

But figuring that out depends on each party's perception about the current situation. Sometimes their perception differs because of the difference in their expectation and past experience about the current situation.

24hrs clock doesn't rely on perception. It conveys the morning/evening part perfectly everytime. 12hrs clock can do this too but people often leave out the AM/PM part for the sake of brevity. Let's go back to post #51 for real example.

My team's reason is obvious so let me clarify my leader's. It's basically:
"C'mon people it's weekend. I'm not expecting you to wake up and go to job during weekend! I mean go, enjoy your weekend, get some rest, have a nice evening. I just asked for a little bit of your time before you go to bed."

My team and leader have different perception about that "9.30". As you can see both reasons hold merit so it's impossible to justify one reason over the other. That "9.30" legit could be interpreted both ways.

24hrs clock simply removes this ambiguity out of the equation.

Meanwhile, there's no question that more than one guy ever has gotten mixed up trying to figure out what time 20 is and missed the appointment by an hour or two.

Thats crazy, the more you know. Thats also additional context that would go towards deciding whether its 8pm or 8am. Its also easier to clarify 8pm vs saying meet at 20

*shrugs*

One guy who by your own example was the only guy out of an unspecified number who couldn't figure out how this works hardly negates the literal millions of times a day people communicate successfully. Meanwhile, there's no question that more than one guy ever has gotten mixed up trying to figure out what time 20 is and missed the appointment by an hour or two.

Just remember 13 is after 12. Even a baby can remember that.

But the argument that saying am and pm takes longer is negated by the fact that you have to subtract. It's not better!

It's only easier because it's what people are used to.

Why do you need to take time doing math?

24hr>>>12hr
Celsius>>> Fahrenheit

Both these are no contest

Year-Month-Day > all other date formats

Since I've used the 12 hour system my entire life, the 24 hour one isn't intuitive.

Year-Month-Day > all other date formats

It's frankly the only acceptable one.

Oh and always four digit year, two digit month, two digit day.

It really doesn't take long to adjust.

On a Global basis, Date Format Standards seem to vary drastically.

The Gregorian Calender however is still the Pre-Dominant Calender that most of the World uses.

China, Mongolia, Korea and Japan know what the hell is up.

Don't forget Taiwan.

No one regularly uses it around me though
