Why hasn’t the Metric world found a better way? I want a clock based around multiples of 10, dammit!

Some people briefly tried that during the French Revolution, but it never caught on.

There is a logical reason why numbers like 12, 24, and 60 are used in a lot of systems. They are highly composite numbers so they have lots of prime factors which means there are lots more options to break them into whole groups.

One benefit of base 12 and base 60 over base 10 for everyday use with things like time is simple factorization. You can divide 12 hours evenly into halves, thirds, quarters, and sixths, and 60 minutes evenly into halves, thirds, quarters, fifths, sixths, tenths, etc. With base 10, you’ve just got halves and fifths.

Yeah, I know all about that, but I don’t think we’ll convince people to change everything to base 12, so let’s go with a base 10 clock.

I just want everything to be switched to 24 instead of 12. Why everyone want to complicate things?

A base-10 unit circle would be abhorrent. 1/2 of a circle is an important concept, but 1/5th and 1/10th of a circle are rarely used in geometry or trigonometry. Meanwhile, a right angle (1/4 of a circle) would require an ugly fraction, and the angle of an equilateral triangle (1/6th) would require a repeating decimal.

Think of 12-hour clocks and 360-degree circles as paper bags. When we’re fucking with angular concepts, you do not want to take those bags off Decimal’s head.

Another benefit of base 12 is that you can count to 12 easily with one hand by using your thumb to count each of the 3 segments on your 4 fingers.

I learned that on that other website prior to the great migration and it blew my mind then.

Wait until you find out that binary counting allows you to count to 31 with one hand.

Pros scale that up to base 60 by counting to 12 and using the other hand to count how many times they have counted to 12.

It was called the French Republican Calendar. Didn’t last very long.

That’s extremely elegant. Plus if you have days of rest every first, fifth and tenth day of the week then you have 3 or 4 days of work in a row at a time (of course im sure at the time they were far more stingy with days of rest)

Because base ten sucks for practical use and anything that needs division.

The French tried at the same time they adopted the rest of the metric system but it just didnt offer much advantage vs changing out clocks.

With digital clocks it would be simpler now.

When I was a kid, I was such a nerd, that I invented my own decimal timekeeping system.

Even wrote a little macOS menubar clock for it — I was dead-serious.

Edit: omg the website still works, even though I never put any real content there …

Edit 2: Found this old explanation I apparently put together in July 2010, according to my image archive:

That’s pretty cool! The French actually had a decimal time system after the revolution, but they eventually abandoned it.

All I can gather, is that the number furthest to the right seems to be 100ms, so the second digit from the right is counting seconds. When those 3 digits reach 000, they’ve counted 100 seconds.

I see 19567288000 currently. If I remove the last zero, that number should be in seconds. So 1956728800 seconds = ~62 years. The year 2023 - 62yrs = 1961.

Maybe it’s counting the number of seconds since a date in 1961? Unix time uses 1970-01-01 but not sure what significance 1961 has.

We should just use second notation for everything.
