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.

are Americans really confused with 15:30?

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.

Only muricans think 24h clock = military time 😂

24hr time is simply superior in every way. I don't get why more people dont swap it.
I changed mine on a whim years ago and never looked back.

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.

12 hour time is a scam created by clockmakers who wanted to save paint.

Bahh.. The full day is 2π.

• 12:00 is π
• 15:00 is 3/2π And so on... Sane people use 2π = 𝜏 instead.

Hard mode: set time zone to UTC (or Reykjavik; it's the same) and force yourself to add/subtract offset hours every time you want to know local time. Also, this forces you to track when exactly daylight saving time starts and stops.

Benefit: you know when space probe stuff happens because they're almost always timestamped UTC. Also, playing Eve Online becomes slightly easier.

In the UK we all (generally) read 24 hour but speak in 12 hour. So we see 15:00 but say 3. Only military peeps talk on 24, and it can sound weird, but people can easily understand them as long as they can parse the whole "-hundred" thing (15:00 being fifteen-hundred)

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... :-(

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.

Only in America do they judge people for using the 24hr clock. Most of the rest of the world uses it. https://worldpopulationreview.com/country-rankings/what-countries-use-24-hour-time

There are several industries that run on 24 hour time outside of the military. Ocean shipping, aviation, and medical care off the top of my head. Want to throw a real wrench in the works? Start figuring Zulu time, especially when time changes happen at different times of the year in different countries or US states that don’t change at all.

Anyway, 24 hour time is so much easier. No making mistakes forgetting to select AM/PM when setting an alarm or reminder, for instance. Even converting it to 12 hour time takes no thought at all of you use it for a while.

I remember when I was a kid who joined a mostly American guild with Discord server in Warframe.

I was so confused when I wrote the time in 24h and the guy I was chatting with seemed genuinely uncomfortable with me writing in military jargon.

(He also believed in ghosts and I had trouble explaining the difference between additive and multiplicative multipliers to him)

There are two comments here:

1. I can count to 24
2. I get confused by 12PM

The real crime is dividing the day into 24h, 60m per hour, 60s per min.

Fuck people who work in logistics right?

Looking at how the clock in Windows defaults based on region, it seems to be mostly the Whiter of the former British colonies plus a few South American countries that use 12h (for computing, at least). The rest of the world are all 24h.

Listen, it's easier, especially when you work with scientific or industrial systems
