Day Length
On Earth, a solar day is around 24 hours.
A recent study done by scientists in America has shown that days on earth are getting longer and in million years from now, a day will last 25 hours on earth. However, the process will take 200 million years in stretching hours of the day to 25 hours from 24.
Modern timekeeping defines a day as the sum of 24 hours—but that is not entirely correct. The Earth's rotation is not constant, so in terms of solar time, most days are a little longer or shorter than that.
24 hours is equal to 1 day.

The 12-hour clock can be traced back as far as Mesopotamia and ancient Egypt. Both an Egyptian sundial for daytime use and an Egyptian water clock for night-time use were found in the tomb of Pharaoh Amenhotep I. Dating to c. 1500 BC, these clocks divided their respective times of use into 12 hours each.
The moon will continue to move farther away from Earth until the Earth's rotation has slowed to the point where both the Moon and Earth keep the same sides facing each other at all times. But the story doesn't end there. Earth will continue to slow down because of tides raised on Earth by the Sun.
Slowing Earth's rotation in turn speeds up the Moon's orbit, which must expand to conserve the total momentum of the Earth-Moon system. The Moon is moving away from Earth at about 1.49 inches (3.78 centimeters) per year.
A day is a time taken by a celestial body to complete one rotation around its axis. On earth day, there are 24 hours. It is just an approximation because the earth day is 23 hours 56 minutes and 4.09 seconds. so it is considered as approximately 24 hours.
THE DIVISION of the hour into 60 minutes and of the minute into 60 seconds comes from the Babylonians who used a sexagesimal (counting in 60s) system for mathematics and astronomy. They derived their number system from the Sumerians who were using it as early as 3500 BC.
Converting Times from 12-hour clock to 24-Hour clock
In 24-hour (military) time, 12:00am is equal to 0000 and is read as “0 hundred hours”.
19:00 = 7:00 PM
19:00 on a 24-hour clock is is 7:00 PM on a 12-hour clock. This system is used throughout the world (not just the military) and leverages a 24-hour time clock rather than the 12-hour AM/PM system known to most English speaking countries.

Times from 1000-2400 with no minutes, such as 1000 (10 am), are spoken “ten-hundred” or “ten-hundred hours”. It's the “hours + hundred”. Times from 1000-2300 with minutes, such as 1345 (1:45 pm) is spoken “thirteen-forty five”.
The traditional American business hours are 9:00 a.m. to 5:00 p.m., Monday to Friday, representing a workweek of five eight-hour days comprising 40 hours in total. These are the origin of the phrase 9-to-5, used to describe a conventional and possibly tedious job.
7am to 4pm is 9 hours - calculate time between any two hours while you type.
So, the time 3 hours after 3 pm is 6 pm.
If it's 7 hours after noon, it's 7 p.m. in a.m./p.m. time and 1900 (or "nineteen hundred") in military time.
Now, whenever a military person speaks that it is 2100 military time, then it clearly means that it is 9pm.

How do I calculate my hour?
First, determine the total number of hours worked by multiplying the hours per week by the number of weeks in a year (52). Next, divide this number from the annual salary. For example, if an employee has a salary of $50,000 and works 40 hours per week, the hourly rate is $50,000/2,080 (40 x 52) = $24.04.
4.30 hours is 4 hours, 18 minutes and 0 seconds. 4.30 hours is also equivalent to 258 minutes and 0 seconds or 15480 seconds.
As an hour consists of 60 minutes, we can convert hour into minutes by multiplying hour with 60. So, for example, if one wants to convert 3 hours into minutes, one can do it by multiplying 3 with sixty which will give 3 x 60 = 180 minutes.
18:00 = 6:00 PM
18:00 on a 24-hour clock is is 6:00 PM on a 12-hour clock.
17:00 = 5:00 PM
17:00 on a 24-hour clock is is 5:00 PM on a 12-hour clock.
Answer: 20:30 hours military time is 08:30 PM in 12 hours clock.
- Determine the start and the end time. ...
- Convert the time to military time (24 hours) ...
- Transform the minutes in decimals. ...
- Subtract the start time from the end time. ...
- Subtract the unpaid time taken for breaks.
Working 40 hours a week has become common for many full-time employees, although different industries have their own standards and protocols that define a standard full-time schedule.
Research suggests that working excessively long hours — usually this means more than 45 a week — is detrimental to your health, physical and mental, in many ways.
Official employer designations regarding full-time employment generally range from 35 to 45 hours, with 40 hours being by far the most common standard. Some companies consider 50 hours a week full-time for exempt employees.
How do you add up time?
Explanation: To add time, you add the hours together, then you add the minutes together.
Multiply calculated time and wage rate
Let's use the same example from above. Your employee worked 20.25 hours. They earn $10.00 per hour. Multiply your employee's hourly rate by their total hours to get their total pay.
The average full-time U.S. employee works five days a week for eight hours a day, totaling 40 hours a week.
7am to 4pm is 9 hours - calculate time between any two hours while you type. 7am to 4pm is how many hours? Typically, you need to find a calculator, calculate the hours worked and then copy it over.
For instance, 1:00pm + 12 = 1300hours, 2:00pm + 12 = 1400hrs and is pronounced 14 hundred hours.
