In human history, has there ever been an example of a non seven-day-week?

The French Republican Calendar is one example- it used "décades," instead of weeks, of ten days' length, from 1793-1806. "The year was not divided into weeks, instead each month was divided into three décades of 10 days, of which the final day was a day of rest. This was an attempt to de-Christianize the calendar, but it was an unpopular move, because now there were 9 work days between each day of rest, whereas the Gregorian Calendar had only 6 work days between each Sunday." -from http://www.webexhibits.org/calendars/calendar-french.html -see also http://en.wikipedia.org/wiki/French_Republican_Calendar, http://en.wikipedia.org/wiki/Seven-day_week, and http://www.hermetic.ch/cal_stud/hlwc/why_seven.htm Jul 13 12, 6:19 PM
