Restless Mind At Work

Have you ever wondered why there are 24 hours in a day? We can say that a day is the time taken for one full rotation of the Earth, one year is the time taken for the Earth to orbit the Sun once, and one month is the time taken for the Moon to orbit the Earth once. All these are definite durations set by nature.

So I figure a year in the calendar was determined by how long it took the Earth to get back to the same position while a month was determined by how long it took the Moon to orbit the Earth. From this, the number of days in a year and number of days in a month can be calculated.

What about 24 hours? Where did that come from? How do you determine that a second is actually a second, a minute is a minute and an hour is an hour? We may have grown accustomed to the duration of 1 second, but what if the actual 1 second was set to be 0.5 seconds? If there was 24 hours in a day and 60 minutes in an hour, then there would be 120 seconds in a minute. These measurements are actually meaningless in nature.

Nevertheless, we use them because time has become so important to us, that we need to measure every single moment/instant that passes, hence the current system.

Point to ponder: There are phrases like "Count your days", "Your days are numbered", "Tomorrow will be another day"... why not "count your seconds", "your seconds are numbered" etc.?

Fine, the restless mind shall rest for now.
