The most basic division indicated in nature is the lunar cycle of 28 days...one moon...one month. If you divide that month into 4 handy divisions of time, you've got 4 weeks of 7 days each. (But why four you may ask?)

But there's another spiritual connection here...deriving from the religions of the East, which are probably more ancient than those of the West. That is the 7 chakras or energy centers in the human body. Those are also analogous to the 7 major colors in the visual spectrum, the 7 notes in our major scale, and various other groups of seven. One finds these patterns over and over again in human culture.

There are also interesting patterns built on the numbers 2, 3, 4, 5, 6 and so on. One finds them in religious traditions, rituals, flags, geometrical forms and symbols (like the 5-pointed or the 6-pointed star). Any study of esoteric spirituality includes the study of geometry and numbers, and the meaning ascribed to them.

No one has yet suggested a 17 day week, and I think the reason why is obvious...it doesn't "sound good". Neither does music that is off-key. A human being recognizes this right away (unless he's tone deaf). A machine doesn't, unless you first program it to take notice.
