Everyone knows that we use clocks and calendars to measure and indicate the time.
Ambrose Bierce said this: 'Day, n. A period of twenty-four hours, mostly misspent.'
We use calendars to organize our days for socially useful purposes, for business, lifestyle and more.
As a society, our time blueprint is the calendar and the clock.
We organize ourselves with blocks of time, called days, weeks and months. (And with clocks - minutes and hours, and so on).
Can you imagine a society without clocks or calendars?
One would be constantly checking the sun for a time bearing, observing stars and the moon at night.

And it sure would be a LOT of fun trying to run a business...
Ultimately though, if you seek to be organized and achieve certain things, you really do want to be familiar with how these time devices work!
It helps to have a good idea how your own body clock works too.
Sometimes you can know the time to the minute without even needing to look at a clock... especially if you're in tune with your own body clock.
Or you can tell yourself to wake at a certain time, and find yourself waking up right at that time.
It's been said that...
"The 1989 Exxon Valdez oil spill off Alaska, the Challenger space shuttle disaster and the Chernobyl nuclear accident have all been attributed to human errors in which sleep-deprivation played a role."
That means that you'd be wise to use clocks or calendars to organize your life - so that you get as much deep, refreshing (and healthy) sleep as possible!

"Experts also say one of the most alluring sleep distractions is the 24-hour accessibility of the internet!"
