A lot of people white knighting clocks in this thread

[–] [email protected] 17 points 1 day ago (5 children)

When I become dictator of the world, this will be the new time unit: https://metric-time.com/

The year will also have 13 months: https://en.m.wikipedia.org/wiki/International_Fixed_Calendar

The year will be 12025: https://en.m.wikipedia.org/wiki/Holocene_calendar

Because these things just make more sense. You will thank me after a few generations, because habits are hard to change.

Team 13-month-calendar assemble!

I haven't done enough digging on metric time, but if it's implemented as a UTC/global time I can get behind that. I'm sick of timezones and DST.

Why the 'IIII' insted of 'IV'?

[–] [email protected] 29 points 1 day ago (1 children)

Prevents confusion between the four and the six: III, IV, V, VI, when the watch is not held perfectly vertically for viewing.

i'm pretty sure that IV is a modern typographic thing

I've also heard that, because in Latin IV is the beginning of "IVPPITER" (Jupiter), there’s a theory that people avoided using "IV" as to not “disrespect” the god’s name. 🤷‍♀️

Also, on a 12 hour clock, 3 sets of four looks clean af I guess, e.g.:

  • I, II, III, IIII
  • V, VI, VII, VIII
  • IX, X, XI, XII

Don't listen to OP's bullshit.

They work for big clock. They're trying to convince you 12 hour clock is useless so they can sell you double the clock.

[–] [email protected] 7 points 1 day ago

Look at this guy, only one clock. I keep two analog clocks in each room, the AM 12-11, and PM 12-11. The way it was meant to be.

Gift from ancient Mesopotamia. Mesopotamians love 12 & base 60. They also liked 7. Those numbers recur in their mythology.

Americans have a weird fixation with 💯. Where Americans might use percentages, I've seen Japanese plot values in [0, 1] (ie, pure proportions).

There's Metric / Decimal Time.

Next time someone makes a post praising the metric system and making fun of people for using imperial units, feel free to call them out as a filthy casual for using a 24-hour clock.

If you want to be mad about time then I'd like to introduce you to a little thing I like to call the Gregorian calendar.

[–] [email protected] 80 points 1 day ago (1 children)

IIRC they counted the bones in their fingers using their thumb and that gives 12. The first sundial was around the equator and there is always light for half a day, so half a day becomes 12 hours.

To count large numbers often one hand was used to count using 5 fingers and the other to count the bones, so you get 5x12 for 60 minutes.

AIUI there was an aspect in the divisibility of the numbers being convenient.

12 is divisible by 2, 3, 4, and 6. 60 is divisible by 2, 3, 4, 5, 6, 10, 12, 15, 20, and 30.

10 is divisible by 2 and 5. 100 is divisible by 2, 4, 5, 10, 20, 25, and 50.

If you want to minimize dealing with fractions, 12 and 60 are far more convenient than 10 and 100.

That's an interesting thought, but I believe it to simply be a coincidence.

The base 12 counting being based on counting the division of your fingers is historically verified, but if the division aspect was so compelling to them you'd expect it to carry forward into their writing system.

By the time you get cuneiform math though, they actually go back to base 10.

As you can see base 12 is not in the written system, or for written mathematics. It just was convenient for counting on their hands.

They used mixes of base 10/base 12 and base 60.

Base 10 would be used go determine the symbols for a specific "digit" in base 60.

So similar to how our 13 is 1 ten and 3 ones, their 13 was the symbol for 10 then 3 symbols for 1. 13 = 𒌋𒁹𒁹𒁹 But 73 would be written 𒁹 𒌋𒁹𒁹𒁹

Which would be interpreted as 1 sixty and 13 ones, or 60 + 13
