@freemo Somewhere sometime Roman time?
@freemo Oh gods, a 7-day week goes back even further than that. It corresponds with the phases of the moon. Full, waning half, new, waxing half. Though it'd not be perfect as it's not exactly 28 days, so some days got added sometimes in the final week. So the concept dates back to like 21st century BC apparently.
Look what you made me do.. I had to look it up and learn something!
@sgul
I propose a new system where saturday and sunday are the only days of the week!
