No idea and don't care there are a bunch of other civilizations who named days and years based on moon and the sun. Just a honorary title because it sounds cool. Why did you name your account redExorcist and not Ronald Mcdonald? Why is a pointless question just person preference that is all.
Seconds, hours, days, months, years are nothing more than measurements of time what you call them is irrelevant.
did you know the moon comes out every month?
after twelve moons, the sun does a complete rotation around the earth?
did you know that an inch was first measured using shadows and stones before the measurement of time and distance were even standardized?
do you know how many moons it takes for a child to form inside of the female body?
why did i name my guild Tuesday? If you can figure that out, you can figure out why im not a blueExorcist or greenExorcist.
Did you know there are seven keys in music? ABDEFG and it repeats back to A? Seven chords in music. Seven hexagons in a honeycomb structure. Seven colors of light.
did you know that pudge in Dota was the original hooker that was later ported into league of legends as some creepy Hooker? Every variation and derivative has a source. I am telling you what that sourcec is. No, not the chaldeans, not gods with the lower case g, not even GOD GOD. there is one God, the God of Israel who has one son. The source of the source. I don't believe in handing out photocopies. Before the chaldeans was the Word.
