    I get the joke, but the sundials of ancient civilisations precluded clocks.

    It is wild how people refuse to use the 24 hour clock. It is so logical and easy. kind of like the metric system……

      It only solves a small part of the issue at the cost of less convenience and consistency. Propose a “metric” time that solves more of this issue problem and I’m all for it

        less convenience and consistency

        What? … seriously, which convenience and consistency are you talking about.

        24h only has one “inconsistency”, going from 23:59 to 0:00. How is that less consistent than 12am being after 11:59pm and 12pm being after 11:59am. Solves all parts of the issue except for one. Which is a lot better than the 12h system.

          Why are the 60 minutes in an hour but 24 hours in a day? What functional difference is there between tne 12 and 24 hour clock? Are you showing up to your friend’s dinner party at 6am because you weren’t sure what time they wanted to start dinner? Are you unsure if your picnic is supposed to be right after midday or the middle of the night? Maybe your friend wanted to meet up for coffee and a bagel when you normally go to bed instead of right before you head off for lunch

            I asked why the am/pm system is apparently more convenient and consistent than the 24h system. I didn’t ask about 24h in a day and 60min in an hour.

            What functional difference is there between tne 12 and 24 hour clock?

            You need 2 numbers and 2 letters to accurately specify time in the 12h clock instead of just 2 numbers. Seems convenient to me.

              You don’t need the am or pm 90% of the time because obviously a lunch date is happening sometime around noon, not midnight. A lunar eclipse or meteor shower isn’t visible while the sun is up, or a midnight snack isn’t happening in the middle of the day. Obviously if you are talking trains and flights, you need AM and PM. But people who are used to 12 hour time don’t want to figure out when 16:00 is, so they don’t.

                Fun fact: Many countries use both systems actually.

                For speaking, it’s quicker to say something like: “The party starts at 8” instead of “The party starts at 20 o’clock”.

                For writing though, you would never use the 12 hour system.

                If you know basic addition and you know how a 12 hour clock functions, then you know how a 24 hour clock functions. If you can’t figure it out, that doesn’t make it inconvenient, it just makes you incredibly stupid.

            Because 12 and 60 are great numbers to divide. You can take a half of it, a third and a quarter and still get whole numbers.

            Iirc the French did try decimal time at one time, it was not convenient.

          This has messed with me for the longest time. 24h just wraps around at 24, simple modulo 24 arithmetic.

          12h? The hour and am / pm wrap around independently, and hence I am always confused whether 12pm is supposed to be midnight or noon. Zero based would have made more sense (with x pm being x hours after noon…)

          Heh thanks for explaining it, I never knew if noon was 12am or 12pm. In German we say “11 in the morning”, “12 o Clock (noon*)” , and “1 o Clock (in the afternoon)”

          But typically we don’t say whether it’s am or pm, it’s clear from context if “i need to be in the work meeting at 9”

          Clocks, TV listings, my work timesheet read 24h times. We read 15:00 as “three” most of the time.

          Btw some software tools (my timesheet for work) differnciate between 0:00 and 24:00. I can work (theoretically) from 0:00 to 8:00 (8h in the night to morning) and from 16:00 to 24:00 (8 hours from afternoon to midnight).

          So 0:00 and 24:00 are the same moment but thought to belong to the next or previous say, respectively.

    24 hour analogue clocks exist. I have a 24 hour watch which only revolves once per 24 hours. It’s a disadvantage though.

    The reason why clocks and watches display 12 hours at a time is so that they have space to show finer resolution of time. If you try to cram 24 hours onto a clock, it’s not easy to tell if it’s 12:20 or 12:30 at a quick glance.

    Most people are not too stupid to be aware of if they are in the first 12 hours or second 12 hours of a day, so they benefit from a watch with 12 hour timescale and finer resolution so that they can more easily see exactly what time it is.

    And for all the dummies posting about 12h vs 24h clocks. In the sense of saying that it’s 1pm vs 13:00. That’s not what this meme is even describing. This is about the physical layout of a clock or watch face.

      I can’t believe this is the first I’m hearing of 24-hour analogue clocks! That’s so cool. But yeah, I see your point about it now allowing for very much precision at a glance.

      I never confirmed this, but I noticed that in parts of West Africa, people wouldn’t say “afternoon” until after 1:00pm. Since greetings were important, I started noticing it more and more when peoe would say “good morning” during lunch at 12:30pm. As if the 12 noon hour is still part of the time segment.

      We’re on Metric time already, the base unit of measure for time in the Metric system is the second. This is decimal time.

      Ugh I can hear it now

      In our relentless pursuit of innovation, we are proud to announce the switch from the outdated 24-hour clock to Metric Time™.

      Effective immediately, your standard 8-hour workday will now be… 8 metric hours.

      That’s 80% of the entire day. Because nothing says “work-life balance” like leaving 2 hours for life.

      Embrace the future. You’re already late.

    Alright, I’m calling a 4.1666666666666666666666666666 metric hour meeting to discuss this!

    The meeting might run to a full 5 metric hours.

    maybe this is because i grew up in a house that had a clock with hands but no numbers, but wth do you mean “the 6 means 30”.

    analogue clocks consists of two progress bars. the numbers are just for convenience.

    Clocks are based on sundials. The little hand roughly follows where a shadow would be. The rest is just what people agreed on made the most sense.
