BEFORE there was DAYS, ........there was "NUMBERS". 1-7 would be the focus here 6 of which God created the heaven as we know it and the earth on which we exist. In the beginning there was no names,how did they begin?Every country seem to have their own calender.
I know about todays knowledge concerning the days and months that came from and are name after Roman and Greek gods and kings.I am speaking about during the time of Adam and Eve when it all first began.When Noah build the Ark.When humankind first became aware of time and how to measure and name days.When there was NUMBERS and not NAMES.
A Day represents a span/an instance of action -what we call creation. To that was added a continuum of lessor days, based on the sun and moon 'locations' at the 'time' of observation.
Days were apportioned based on recorded lunar cycles. Nearly all ancient calendars are exact, having 28 'days' in a single lunar rotation. the Gregorian is an inaccurate format, activated 2,011 years ago.
Interesting enough, nearly all calendars of the ancient world were based on crop cycles, as it takes 28 days to sprout vegetation, grain etc. 84 for grain to come harvest, etc. Also, it takes a female mammal 28 days to cycle their womb for having a child.
Now, we no longer a required to live by days or celebrate times/seasons/dates. We have access to Days once more.
