hy are there 24 hours in 1 day?

Answer 1

There aren't 24 hours in a day. In fact, no day is 24 hours long. The average length of a day is just short of 24 hours, so we use 24 hours as the average.
In fact, there are many factors that contribute to how long a day is. Large earthquakes and tsunamis can literally extend or shorten a day by slightly altering the earth's rotation (this happened a few years back). While this could conceivably cause major problems, the suns gravity helps to put the earth back into its place.

There were 24 hours in a day. An hour is defined as 60 minutes, and a minute is defined as 60 seconds. 1 second was originally defined as 1/86,400 of a day. A day is well known to be the time taken for a celestial body to complete a rotation on its axis, and it was known that days are of varying length. So the "day" used for the definition of the second was the mean average length of days from 1750 to 1892.

Today, a second is much more precise, as are the minute and hour. Clocks are nowhere near as accurate as the definition of a second, so that fraction of a day doesn't make much of a difference to them. Basically, how it works is that seconds, minutes, and hours are precise measurements of time. Even though they were initially based on the time in a day, that is no longer the case because a day is not precise.

Answer 2

I think it has something to do with the fact that the Babylonians like the number becasue it was easily divisible by many numbers, same reason there are 60 seconds in a minute. . .
Just reasearch the Gregorian calendar

By the way if there was 30 hours or 15 hours, or just 5min in a day then that is how long it would take the earth to revolve, time is an arbitrary invention of man.

And it takes a year to fully orbit the sun

Answer 3

check out this web site it really does make sense once you try it.
I always thought 24 hours because that how long it took a sun dial be return to the exact spot again with it's shadow 12 times in sun light and 12 in moon light until that day ended. But seriously check this page.... http://www.andrewtobias.com/bkoldcolumns/010226.html

Answer 4

It is the nearest whole unit to full earth rotation.

I believe humans (in absence of light/clocks) adapt to a 26 hr day but this would cause light creep and constant moving of clocks.

Answer 5

Because that is the amount of time it takes the earth to turn around one time.

Answer 6

yes there 24 hrs in one day

Answer 7

Because that is how long it takes for the earth to make one full revolution.

Answer 8

Because that's how long it takes the earth to rotate. (Unless, you are asking abt the origination and length of hours).

Answer 9

it's how long the earth take to revolve around the sun
