Before going to sleep last night I started to think. As you can tell by now, that is the time when I get most of my interesting thoughts that I share with you.
Yesterday I was thinking about why weeks have seven days and what if we had 5 days a week or had 8 day weeks in a month, with three rest days after each other. It is a bit complex, so when I woke up I checked around and this is what I found on the seven days week pattern.
The seven-day week was established as imperial calendar in the late Roman empire and furthered by the Christian church for historical reasons. It was used by the British Empire and spread world-wide. We also are well aware of the religious significance of the number 7
Now this is interesting
" One viable theory correlates the seven day week to the seven (astrological) "planets" known to the ancients: Sun, Moon, Mars, Mercury, Jupiter, Venus, and Saturn. The number seven does not seem an obvious choice to match lunar or solar periods, however.
A solar year could be more evenly divided into weeks of 5 days, and the moon phases five-day and six-day weeks make a better short term fit (6 times 5 is 30) to the lunar (synodic) month (of about 29.53 days) than the current week (4 times 7 is 28). The seven-day week may have been chosen because its length approximates one moon phase (one quarter = 29.53 / 4 = 7.3825)."
From another site I found this:
"The first thing to understand is that a week is not necessarily seven days. In pre-literate societies weeks of 4 to 10 days were observed; those weeks were typically the interval from one market day to the next. Four to 10 days gave farmers enough time to accumulate and transport goods to sell. (The one week that was almost always avoided was the 7-day week -- it was considered unlucky!)
The 7-day week was introduced in Rome (where ides, nones, and calends were the vogue) in the first century A.D. by Persian astrology fanatics, not by Christians or Jews. The idea was that there would be a day for the five known planets, plus the sun and the moon, making seven; this was an ancient West Asian idea.
However, when Christianity became the official religion of the Roman empire in the time of Constantine (c. 325 A.D.), the familiar Hebrew-Christian week of 7 days, beginning on Sunday, became conflated with the pagan week and took its place in the Julian calendar. Thereafter, it seemed to Christians that the week Rome now observed was seamless with the 7-day week of the Bible -- even though its pagan roots were obvious in the names of the days: Saturn's day, Sun's day, Moon's day. The other days take their equally pagan names in English from a detour into Norse mythology: Tiw's day, Woden's day, Thor's day, and Fria's day.
The amazing thing is that today the 7-day week, which is widely viewed as being Judeo-Christian, even Bible-based, holds sway for civil purposes over the entire world, including countries where Judaism and Christianity are anathema. Chinese, Arabs, Indians, Africans, Japanese, and a hundred others sit down at the U.N. to the tune of a 7-day week, in perfect peace (at least calendrically!).
So dear is this succession of 7 days that when the calendar changed from Julian to Gregorian the week was preserved, though not the days of the month: in 1752, in England, Sept. 14 followed Sept. 2 -- but Thursday followed Wednesday, as always. Eleven days disappeared from the calendar -- but not from the week! "
More infomation:
" it's true that the average time from, say, half-moon to full moon is 7.383 days, but this is less than 12% closer to 7 than to 8. (Possibly mindful of this, the Romans had an 8-day week.) In any case, the exact moment of half or full moon is hard to judge. The moon determines the month, not the week (the very word "month" has been related to "moon" for thousands of years; in Sanskrit they are the same.) "

I did not bargin on so much information when I first thought of it yesterday, but I think in summary we can adjust our weeks to more or less days per month as long as we can figure out how it fits in our lives. At this moment the seven day week is a set pattern that would be hard to change, but if we say get all destroyed by a nuclear war and we have two hundred people living with roaches (yes they do not die), then we can adjust the week as we perfer.
I leave this post for Caffinated to analyze and give me a summary (or anyone with more brains than her).
I also thought about Bizzaro worlds, but I will leave that for another post.
