Sometimes time becomes a villain if you misuse/waste it. If you don’t want to waste your time then use this time calculator. It will increase your productivity and also you can save it. Then you can utilize it for something else.

Measurement of Time

There are many units we use for measuring time. Like second, minute, and hours. Some very small units are picosecond, nanosecond, microsecond, and millisecond. These units are least used by humans. It is using in special slow-motion devices.

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 up then you have a quarter, leap year, decade, century, and millennium. The basic or standard units are minutes and seconds.

History of Time

Today we have a clock and watches to watch the time. It’s very interesting to know how ancient people watched time without any modern facilities. Egyptian Civilisation first launched the concept of measuring time and units like hours, minutes, and seconds. They only developed 24 hours day concept.

They used nature as a clock. The day was divided into 12 parts. Ranging between sunrise and sundial. After that, they modify it and introduced new methods to measure time. Then people started using an hourglass. That includes two parts. One portion was filled with sand and other one is empty. For measure time, we have to keep a filled portion upside. While the empty potion remained downside. So, time progress was measured using the rate of sand falling from upper part to 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 do the time calculation using a Time calculator.
