If the day started at 1:00 then by the second hour you would be at 2:00, even though only 1 hour has passed. Effectively the day starts at 0. In fact in 24-hour time that is how it’s depicted, 00:00 with midday being depicted as 12:00, so it isn’t confusing
It’s the same logic that was used by ancient astronomers to arrive at 360 degrees for a full revolution.
The math is easier if you have to do it by hand.
These are called “superior highly composite numbers” apparently https://en.wikipedia.org/wiki/Superior_highly_composite_number
Well it’s because noon means nine because the day starts at six o’ clock, so three is noon, but we use it to mean twelve which is closer to midday, obviously
Hour hand -> hour = n
Minute hand -> minute = n * 5
It makes sense, there’s just an algorithm attached to each pointer.Hour -> 3 = 3
Minute -> 3 = 3 * 5 = 15The first clocks didn’t have a minute hand though.
Relatively funny but gets worse the more you think about it.
The 6 stands for 6, not 30.
When we have AM and PM it would be dumb to have 1-24.
1 is the end of the 1st hour. 2 the end of the second. This is why it starts at 0.
0
She’s a witch!
The 6 means 30, both of which also mean 1/2
Somebody never had a clock with roman numerals and it shows
I remember getting into an argument with a grade school teacher over IIII because most such clocks put that for 4 instead of IV because of some fuckin reason
I despise these so so much. IIII was historically NEVER correct. Some doofus decided to put that on a clock because it looks more symmetrical with the VIII on the other side. Terrible reasoning.

Weird, I’ve seen many analog clocks with Roman numerals but always IV for 4.
It’s actually called the “clockmakers four” or “watchmakers four.” it’s a thing.
Yeah I looked it up and saw it is a thing, and it’s interesting. I wonder if the clock I’m thinking of was just a really cheap one that was labeled as you’d expect based on Roman numerals or whether some just didn’t follow it.
To be fair, Google searching Roman numerals clocks give you about a 50/50 distribution.
I wasn’t aware of this either and I suspect we’re not alone. It’s not highly noticeable and if there’s a 50-50 chance won’t even see it…
False. I had a clock that used IIII instead.
Your clock having it doesn’t change that mine didn’t.
Somebody gave me this clock…I just need the time.

Clocks should use 24h format. AM/PM is completely useless.
No it’s not, with a 12h format on an analog watch you can use the sun to find true north. It is also easier to read it when the hands have double the amount of degrees to indicate the number.
Edit – digital watches should use 24h, I fully agree, maybe there was a misunderstanding because it’s analog watches we’re talking about here and these could stay 12h IMHO
How do you find north on a 12h face that wouldn’t work with a 24h face? Because the method I know, requires correcting for the 12h circle.
Yeah, that’s the method I know.
Divide the angle that is made in half
And that’s how you correct for the 12h face.
Thought as much but never had any experience with 24h watches, so no comment on this from my side :)
I have never seem a 24h wrist watch (I know they exist) aside from extremely seldom as wall clocks
I’ve looked for them, but they’re very hard to find and expensive too. You can’t just slap a 24h face on a 12h mechanism, so it’s all custom and produced in low volumes. (I think it’s technically possible to convert a 12h period into 24h by switching out a single gear, but that might ruin your minute hand too? I’m no clock maker.)
How the heck do you find north based on your watch? I’m pretty good at knowing where north in based on where I am.
I live in north Manchester so I know Manchester is south. Or I can look at the sun if not midday and figure it out.

I live in north Manchester so I know Manchester is south
What if you go on a trip to Thailand and get turned around in the jungle?
Or I can look at the sun if not midday and figure it out
That gives you a very approximate direction.
It’s useless in the jungle, as you can’t see the sun.
Thanks.
I don’t generally go places like that, but if I needed to be aware of north I would take a compass.
Still good information though.
It’s the same method.
The distance between the sun and 12 is divided by two, because the clock face only shows half the day.
If we had a clock with 24 hours in the circle and used the same method, it’d be the same as pointing at the sun and saying: South is where the sun will be at noon.
The french:
Goddamn metric time
Why the ‘IIII’ insted of ‘IV’?
Prevents confusion between the four and the six: III, IV, V, VI, when the watch is not held perfectly vertically for viewing.
Actually very common in watches with roman numbers iirc
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, e.g.:
- I, II, III, IIII
- V, VI, VII, VIII
- IX, X, XI, XII
looks clean af I guess.
May as well just go with VIIII then. Or maybe 9.
Since the IIII usage is common in the Middle Ages and even into the Early Modern Period, when nobody believed in Jupiter, that is obviously just something somebody made up.
It could have also started from that and continued on despite people not knowing the reason, no? I do agree that it’s quite silly and unlikely, though.
Why does everything that comes from Switzerland always seem to be owned by Swatch? Do they not have any other brands there?
Now I really want a .beats watch. That’s so retro cool.
If you’re ok with a screwdriver, you can mod a Casio F91-W and add a .beat watchface https://www.sensorwatch.net/docs/watchfaces/clock/#beat-time
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
I’ma start a revolution where we use duodecimal metric for everything, including time.
That’s how we ended up with 12 months of varying length in a year and it’s a mess.
It’s a problem no matter how you divide the year
That’s why I propose changing the orbit of the earth, too
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.
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.
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.
I’d love to have a 13-month calendar.
Seems a bit odd to not use a base 10 number of months.
Redefining the definition of a second sounds very problematic.
If you make the 13th month a holiday with no work, you have my support .
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.
Nah, instead we’ll go back to the local noon standard where the time zone is set by when the sun is directly above you. Instead of a couple dozen time zones we’ll have thousands.
At least our hours are the same length regardless of latitude now, so let’s be grateful for that.
I only recently learned the etymology of the word: “second”
Its name comes from being the “second” division of the hour, with the minute being the first.
It’s funny how we go straight to metric when dividing seconds
I’ll see you in 5 firsts, 2 seconds and 7 thirds.
Zero zeros?
I honestly hate this.
It’s like bad world building for some throwaway fiction story.
