Time being very important. It sometimes becomes a villain if you misuse/waste the time. If you don’t want to waste your time then use this time calculator. It will increase your productivity and you can also save time. And that you can later utilize for something.

Measurement of Time

There are many units we use for measuring time. Like second, minute, hours. Some very small units of time are picosecond, nanosecond, microsecond, and millisecond. These units are least observable by humans. Special slow-motion devices are used for it.

Similarly, there are some units that we are using to measure a very long time. Like an hour, day, week, month, and year. If you go more beyond then you have a quarter, leap year, decade, century, and millennium. The basic or standard unit of time is minutes and seconds.

History of Time

Today we have a clock and watches to watch the time. It will be very interesting to know how ancient people handled time without modern facilities. The concept of measuring time and coining of the terms like minutes, seconds, and hours was first done by Egyptian Civilisation. They only developed the 24 hours day concept.

They used nature as a clock. The day was divided into 12 parts. Ranging between sunrise and sundial. After that more modification was done. Humans developed and introduced new methods to measure time. Such as the use of hourglass. That consisted of two parts in which one portion was filled with sand. The filled portion was kept the upside. While the empty potion was kept downside. Time elapsed was measured using the rate of falling of sand from the upper part to the lower part.

Unit of Time

One minute contains 60 seconds. An hour has 60 minutes. Therefore, one hour ultimately has 60 x 60 seconds = 3600 seconds. For one day it will be 3600 x 24 = 86,400 seconds. As one day has a total of 24 hours. Similarly, you can find out your calculation by this basic conversion. Time calculator can do every type of time calculation.
