      Most of that time is irrelevant to me. Let’s just start it in 1970. And I need more precision, so can we do milliseconds instead of seconds?

    The numbers on the clock actually make a lot of sense.

    12, 24 and 60 are highly composite numbers (https://en.wikipedia.org/wiki/Highly_composite_number).

    Imagine using numbers in a world where most people have no real understanding of fractions.

    That is also the reason why you see the same or similar numbers as common screen refresh rates. 24, 48, 60, 120 and 240.

    The 12 hour clockface design is that way because it is a similar design to that of a sundial, so people did not need to learn a new way to read the time. This also meant that for readibility reasons it was beneficial to only have 12 numbers.

      60 in particular is a superior highly composite number, 12 divisors compared to a paltry 8 for 24.

      Everybody loves composite numbers, but I’m missing the point in which this is advantage in the context of time. The only situation I know of where time needs to be divided is in paid work, and in this case it’s always converted to base 10 money.

        The decimalization of money is its own fun history, with a lot of different countries undergoing their own transitions at different times.

        The Spanish dollar, which was the world reserve currency in its heyday, was divided into 8 reals (see how pirates used to refer to money in the form of “pieces of eight”) but issues with the supply of silver led to the introduction of the lesser real de vellón, which eventually settled at 20 to the dollar after over 100 years of uncertainty and confusion.

        Geometry.

        The first clocks were sundials, which worked by putting a line on the ground. As soon as you comparing two different lines on the ground, you are doing geometry to represent time.

        When you start messing around with geometry, you need an easy way to describe the angle of an equilateral triangle. 1/6th of a circle, or 1/3rd of a line. Trying to represent 1/3 or 1/6th in base 10 is fugly. Trying to divide a circle into 10 equal sections is just as fugly.

        Dividing a circle into 6 equal sections is trivial: after you draw the circle with your compass, walk the compass around the perimeter. You have just inscribed a hexagon.

        You’re still missing the angle of 1/4 of a circle: the angles of a square. Those are pretty important in geometry as well. It’s fairly trivial to draw another 6 points between the first 6 on your circle.

        We use a 12-hour clock because of basic geometry. The 360-degree circle is the bastard child of basic geometry and a base-10 number system.

      there’s 86400 seconds in a day. If we use a new unit that is slightly shorter than a second as a metric second, we can do 100000 metric seconds a day, with 100 metric seconds per metric minutes, and 100 metric minutes per metric hour, and each day having 10 metric hours.

      Your 1 hour activity now takes 0.5 metric hours (it might be 20% longer, but that’s arbitrary anyways, we rounded them to the closest hour anyways)

      We are only used to the current system because we have been using it.

    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”.

      Yup, that’s why we still don’t have any clocks to this day.

    My pet theory is (circa 10000 BCE) that ‘houses’ and ‘hours’ are related words, the 12 hour clock matched the zodiac, each hour/house was 1 Assyrian ‘watch’ and they had no trouble day or night (constellations at night, sundial during the day), they were easy to build, easy to communicate, easy to understand and efficient.

    Then the Egyptians stole the technology (Circa 6000BCE) said ‘12 hours in a day? I got you bro’, fucked it up and it all went downhill from there.

    Feel free to quote me in your prize winning scientific paper.

      How important is it to your theory that “hour” is related to “house” in… ancient Assyrian language? Because they’re completely unrelated in English, “house” coming from Germanic hus and “hour” coming from French ore. If we look at ancient Greek, the two are hoora for “hour” and oikos for “house”. I think English post-vowel shift has to be the first language where those two even sound similar.

        Not central, just suspicious, but… this is ‘house’ as in astrological house as in the first part of the word ‘horoscope’, not house like a house you live in.

        My background in linguistics consists of a couple chompsky soft-science books and a love of tolkien, but if you actually know something and wanna chat I’d honestly love to dig in on this seriously. DM me.
