I think we’d all be saner if we opted for an eight-day week: Five days for professional working, one day for rest and relaxation, one day for household maintenance and administration, and one day for working toward larger, non-professional goals. (Hopefully all days for socializing of various kinds.) The Romans used to do it. And the seven-day week, its salient place in the Genesis creation story, has no observable basis in the created order, although it is probably based on an old, inaccurate understanding of that: At least two ancient civilizations, Sumeria and Babylonia, explicitly based their seven-day week on how many planet they thought there were—Mercury, Venus, Earth, Mars, Jupiter, Saturn—plus the sun and the moon. So why keep it, other than cultural inertia?
I suppose I have to figure out how to dovetail an eight-day week with a 365-plus-day year with a proposal for year. (Ten four-week months plus a five-week month plus a five-day party?) And of course, if we can’t even muster the political will to eliminate the Daylight Savings Time switch…
