Our time measurement system traces back to civilizations that used base 12 math, counting the finger bones on one hand with the same hands thumb(12). and groups of 12 with the fingers/thumb other hand(60)

This set back all the progress I’ve made while trying to read a clock

If you're having a problem with it you can buy a 24hr clock

Only confusing this about a clock is telling whether it’s 6pm or 6am some say, but take a fucking look outside, it’s not hard to tell

analog clocks give you quarterly estimates of time as 15 minute intervals. Minute by minute isn't always needed. The position of the arms is all that's needed. Face clocks also describe direction: 12 O'clock is straight up. 1 o'clock slightly to the right and so on. 6 o'clock straight down and 7 o'clock slightly down and to the left. Then all the way back to straight up to 12 o'clock. What is at your 10 o'clock? "Red Baron flew up from his 4 o'clock and shot out the wing."
Digital clocks are fine but the second hand is necessary to take a pulse without a battery. Also reading an analog is reading time as a pattern and some people read time faster by shape than they can read a group of numbers.

The 24 hour clock came before the 12h, the guy who invented the clock was really into shadows.

From a quick Google search:
The first known reference to a standardized second (time unit) was around the year 1000 AD, by the Persian scholar al-Biruni when he gave the times of the new moons of specific weeks as a number of days, hours, minutes, seconds, thirds, and fourths after noon Sunday.

Prior to that year, the second was not a common unit of time; Hipparchus (c. 150 BC) and Ptolemy (c. AD 150) subdivided the day sexagesimally (into sixtieths) and also used a mean hour (1⁄24 day), simple fractions of an hour (1⁄4, 2⁄3, etc.) and time-degrees (1⁄360 day or four modern minutes), but not modern minutes or seconds. The Babylonians did not use the hour, but did use a double-hour lasting 120 modern minutes, a time-degree lasting four modern minutes, and a barleycorn lasting 3-1⁄3 modern seconds.

The progression to al-Biruni's minute and second was a pretty natural one; the day had already been divided into 1⁄24s (hours) by established precedent, and 1⁄60ths were commonly used as divisors, so division of each hour into 60 minutes and subsequently dividing each minute into 60 seconds was straightforward arithmetic. 1⁄60ths were common because 60 is so highly versatile - it can be easily divided many different ways to yield various fractions of the major unit; 60 is equally divisible by 2, 3, 4, 5, 6, 10, 12, 15, 20, and 30.

In addition.

A seconds pendulum is a pendulum that has a period of two seconds, which means it takes one second for the pendulum to swing in one direction and one second for the return swing. It has a frequency of 0.5 hertz (Hz) and is approximately 99.9 centimeters long, or almost one meter.

Seconds pendulums were commonly used in pendulum clocks and to measure gravity. The period of a pendulum can be used to calculate the Earth's local gravitational acceleration because of the presence of the acceleration of gravity in the pendulum's periodicity equation.

Pendulum clocks were the primary time standard for homes, offices, factories, and railroad stations in the 18th and 19th centuries. They were more accurate than other timekeeping methods, which allowed for a faster pace of life during the Industrial Revolution. However, by the 1930s and 1940s, they were replaced by cheaper synchronous electric clocks. Today, pendulum clocks are mainly kept for their decorative and antique value.

Or just use a 24 hour clock lol. 12/12 clocks are just sundials. But there’s also moondials, which would be used to tell time at night.

"😢 I'm so ignorant I can't read a clock, and definitely I don't know the history of clocks"

[andrewflowers]

Here in Thailand every day is 12 hours long.
We describe time in hours after sunrise & sunset. So easy.

[yumikogita]

Telling the time is only hard if you're stupid

[nehas]

Nah if we make it easy ppl are gonna understand it😮

[soonnah]

How on earth do people actually not know how to read a clock?...

[dillyDillzmuaythailife]

I to this day still vaguely understand the clock, like we have one in our kitchen, but once phones came out and microwaves with digital time yeah the need for clock was over

[stanleystrem]

People need to learn how to read clocks

[Wolfmandipper]

Im certain that the 12 hour clock had nothing to do with some one being a maniac and everything to do with the sundial and how after a certain time the sun dial no longer has sun also do you realize how impossible it would be to read a 24 hour wrist watch the numbers would be so tiny

[jamiesmith]

It’s based of of latitude lol he didn’t really have a choice

[JamieKim]

I have my dad's clock he got in fhe Air Force. It's in military time.

[billyhendry]

The day starts at 00:01 just like centuries etc. Do.

20th century started in 1901 not 1900

[adamblancas]

It makes sense. Sorry math is hard for you
