How Many Times Do The Hand Of A Clock Overlap In 12 Hours?


We all know that the hands of a clock overlap nearly every hour, but how many times does it actually overlap and does it overlap every hour. Well, these along with some other related questions are what we’ll be answering in this very video, so without further ado, let’s get right into it!

The clock hands cross each other/ overlap a total of 11 times in 12 hours

How Many Times Do The Clock’ Hands Overlap In 24 Hours?

In a 24-hour period, the hands of a clock would overlap for 22 times, as it takes nearly 1 hour 5 minutes and 27 something seconds for the hands to overlap and in a 24 hour period that would mean leapin over 2 hours in which the hands won’t be able to overlap!

Is There A Special Equation Or Time After Which The Hands Overlap?

Yes, the hands of a clock overlap nearly after every 1 hour 5 minutes and 27 seconds, and the reason why the hands don’t overlap 12 times is because of the fact that those extra 5 minutes and 27 something seconds when combine to form more then an hour which means leaping over an hour of hands overlapping

Clocks Ticking: Why Is it?

Ticking is one of the most renowned features of a conventional clock and though there are quite a few clocks that don’t make any kind of ticking sounds that you can buy for yourself, there are still quite a few that we use in our daily lives which are fond of making these conventionally popular sounds. These sounds often raise curiosity in minds of many that what is it that actually makes a clock tick and why is it that it produces. So, today we decided to look into that very aspect of clocks and talk elaborately about it so without further ado, let’s get right to answering the basic crux of this article, Why do Clocks Tick?

The second hand of a conventional analog clock moves and stops every second for a bit, this leads to the small vibrations within the glass of the clock and prompts the “Tick” sound that we are so fond of hearing every so often.

This is the case with quartz clocks that produces a single “tick” sound with every moment. These are the clocks that we usually use at our homes and the ones that are usually run on batteries. However, one very important thing to note is that mechanical clocks ( Not that common nowadays ) do not work like this and in fact, they don’t make one “Tick” sounds but they go on to make two alternate sounds, one a bit sharper than the other and that is exactly where we often get confused and think that the clocks that we use nowadays at our homes also work this way. But this is not the case as most of the clocks that we use at our homes aren’t mechanical in nature but are rather battery-powered clocks which produce only one sound “The Tick Sound”

Are There Two Alternating “Tick” And “Tock” Sounds?

No, the clocks that we use nowadays in our daily routine are battery run quartz clocks that only produce one sound “Tick”. However like we just discussed above, the mechanical clocks ( that are not that common anymore but were a while back like the pendulum clock ) are the ones that produce two alternating sounds “Tick” “Tock”

The actual gears inside the clock move forward and backward while a doubly sided fork is held above them to make them move forward ever so slightly( Illustrated in the GIF above ). When the fork strikes the right side of the gear a slightly sharper sound is created as it engaging the outer side of the spike, which we are conventionally familiar by the name “Tick” and when it strikes on the left side engaging the inner side of the spike producing a comparatively higher based sound which we conventionally

So in case you have a regular quartz battery-run clock, it wouldn’t be wrong to state that your clock only produce a single sound of “tick” and if you think otherwise its basically a result of a psychological effect which has been embedded over our years of hearing the clock and in reality these clocks only produce one sound over and over again and if you focus on the hand of the clock whilst it’s moving try clearly hearing the sound which is being made, you will be able to realize it is one sound “Tick”

Why Do We Use 12 Instead Of 0 On The Clock?

It goes back to the ancient Sumerian/Babylonian base 60 number system. They didn’t have the number zero back then as it hadn’t been invented yet. And hence it was ultimately decided to settle on 60 after some extensive discussions and calculations by the mathematicians of the time. As 60 easily breaks into 2 lots of 30, 3 lots of 20, 12 lots of 5, 4 lots of 15, 2 lots of 15 lots of 2, and so on

This decision proved quite helpful for them in conducting their daily trade as people of the time weren’t mostly educated to deal with fractions and this proved quite helpful. This was precisely the same reason for why 360 degrees were chosen.

So simply put 60 minutes in an hour and 12 blocks of time that we regard as an hour in a day and 12 at night was quite convenient, Moreover this basically is a throwback to the Babylonian system that gave birth to this very concept.
