The 6 means 6, 18, AND 30.
At least they are all divisible by 6.
God I’d hope so. Imagine how bad you’d have to fuck up time to make it not :)
Oh also the hours will start at 1 and the minutes will start at 0
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.
Only noobs start counting at 1. Midnight = 24:00 = 00:00
Let’s just switch to metric time. https://metric-time.com/
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In our relentless pursuit of innovation, we are proud to announce the switch from the outdated 24-hour clock to Metric Time™.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.
Holy shit, that actually looks so neat and organized, I want it 😭
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.
Surely you mean common refresh rates like 23.976Hz (NTSC), 25hz (PAL & ATSC), 50hz (PAL & ATSC), 59.95hz (NTSC), 100hz (PAL+) and 144hz, right? /s
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.
Haven’t seen this one this week. Thanks
We will also use 3 sticks to tell the time.
Time is linear. But this will be circular.
Time …line? Time is not made of lines. It is made of circles. That is why clocks are round!
Why don’t I ever get the fucking sniper rifle?
24 hours cause Egyptians split their sun dials and star decans into 12 parts each (probably cause 12 is divisible by 2, 3, 4, and 6) which the greeks later turned into equal length hours (before the length would change over the year)
60 minutes due to Babylonian base-60 math
12 hour format is just tradition at this point, but derived from the sun dials which only worked at day, so half the time, and the star decans which only worked at night, so the other half.
pretty much every country except the US uses the 24h format on digitial clocks now
also the dude in the meme was kinda right: the day will be divided into 12 segments. and the night will too. at least originally
This all originated from the Ancient Sumerians btw. They passed it down to Babylonians.
Edit: A bit of history from what I learned from listening to Fall of Civilizations in the shower.
The Ancient Sumerians invented this sexagesimal system because if you look at your hand, you notice 12 knuckles (this is obviously excluding your thumb, as that is used for counting each knuckle), and with your other hand you will raise a single finger for every time you finish counting past 12 knuckles on your left hand. So raising your thumb is 12, thumb and index is 24, and so on, until you reach 60.
Came here to say this, you said it far better than I would have! Great addition with the edit.
It’s called a “highly composite number!” I read up on a lot of this stuff while learning about numerology and other esoteric spiritual traditions!
Its possible to create a new time format/ system, the problem is how to standardise it everywhere
Easy, use the metric time.
9:30 PM would just become Hour 89.58333333/100 of the day 😉
No use imperial, eg. 1 gallon is equal to 2,4899 feet mutliplied with 8,67763 nuggets, therefore you need to work five big mac longer
It has been done and it is called swatch time.
Beat/Swatch time was itself inspired by French Republican time.
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.
This is what the minute and second hands are for, though
You could get a jump hour watch, meaning the hour isn’t a slowly moving hand but instead jumps from 6 to 7 with a jump, avoiding potential mixing up of hours, it would make it easier to read those 24h
Like this watch
Edit: The original watch linked is a weird one, it’s not a jump hour watch but instead it has a jumping dial to turn it from a 12h to a 24h, very neat! I can’t seem to find a 24h jump hour watch apart from this 30k breguet lol
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.
If 12 is better than 24 we should build 6 hour analog clocks already!
It is wild how people refuse to use the 24 hour clock. It is so logical and easy. kind of like the metric system……
You mean like metric time?
Metric system should be replaced with something base12 thh
First thing I change on every electronic device I buy.
And really annoying when something only has 12hr mode
I don’t want to believe that time goes on for that long.
I’d rather a 6 hour clock.
I’d prefer base 10 time than base 12. Until then I’ll just keep with am pm
I’d prefer base 12 for everything
We should all also use GMT and forget about time zones.
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
“This doesn’t solve all of the problems instantly so I refuse”
Classic
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.
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.
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…)
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
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.
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.

1 metric second would be a little less than half our current second.
Global electricity output would instantly more than double!!!
Dammit, that wasn’t supposed to post yet. I’m still in the process of revising! Lol.
Not to worry, we will use the Babylonian watt for
megaimperial-tonne-fortnights to come.
I get the joke, but the sundials of ancient civilisations precluded clocks.
Sundials also didn’t work very well at midnight for some reason, what’s ya point?
You’re just not holding the flashlight properly.
If you hold the flashlight right they work 100% of the time.
Instructions unclear, I think my fleshlight is broken…
Dial it back a bit son
Back in, or back out? Please be clear or I’ll have to keep trying both ways. Over. And. Over. And. Over. Aaaannn…fffff.
<connection reset by peer>
That’s when we bring out the moondial.
The firedial works every night.
Sundials also didn’t work very well at midnight for some reason, what’s ya point?
Noon is the center of the dial. Midnight is just the opposite of noon.
I cannot tell if this is sarcasm or not. This is peak Poe’s Law.
That’s why for a long time, and even longer in the Royal Navy, the new day started at noon and not midnight.
“Precluded” means “prevented” or to “make impossible” ❤️
Oh hot damn, first time I used that word.
Maybe presaged?
Preceded maybe? Precluded sounds like it should mean something similar for sure tho
Predated
It’s all the Babylonians fault
Those fuckers could count to 60 on their fingers. Witchcraft!
Using binary, we could count to 1023 with 10 fingers but only 511 with 9 fingers
Boys could count to 2047.
Well… This post sent me down a rabbit hole -> Unequal Hours if anyone else is curious.
Yup, that’s why we still don’t have any clocks to this day.
Alright, I’m calling a 4.1666666666666666666666666666 metric hour meeting to discuss this!
The meeting might run to a full 5 metric hours.
“Hey sweetie, please come home by Hour 89.58333333/100 otherwise I’m gonna have to ground you for a week, love you!”
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.
Thanks Obama
Keep it simple and just measure in terms of seconds since the Big Bang. The current time is 435,884,579,968,052,736 seconds, easy peasy
Maybe where you’re sitting. But my frame of reference has had slightly different time dilation than yours.
This would go great with my idea of everyone having a GUID instead of a name.
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?
Nah just use Unix time
technically that is 64 bit unix time.
The big bang was definitely not in 1970
The big bang was definitely not last Thursday
They had to pick a period where 32 bits would last long enough. If they had started with 64 bits, they could have used a start of time much further back.
