It seems to have two origins. I'd say the primary origin is Jewish, the Jewish Sabbath practice. So to have a Sabbath count required that you maintain that weekly cycle, that's one origin. The Romans also observed a planetary week where they identified each day of a seven-day cycle with one of the planets, including the sun and the moon as planets.

That's where we get names like Sunday, Monday, Moonday, Tuesday, which is different, Mars, etc. So those are the two origins. And those two calendar systems kind of met in the Roman Empire. And then... initially through Christianity, spread to other parts of the world, but not instantly and not evenly over the course of the next 2,000 years.

Right. I mean, you know, you could interpret that as it's been imposed on all of us, or you could interpret it as I think your question implies, that there's some special utilities and special value to having a seven-day cycle. Having a seven-day cycle doesn't necessarily mean that you rest one or two days out of seven, though that's typically how it's used.

But yeah, counting cycles of seven days lasts. So whether it lasts because it's been imposed or because of habit or because of utility, I think is an interesting question.

Well, there was and there wasn't within the Bible, right? The Bible says that God rests on day seven, but doesn't say that then God observes a cycle of seven days. It doesn't say then every seven days God rests, and doesn't say that therefore people rested every seven days. And it's not clear from Genesis.

I mean, if you just read the Bible from the beginning, you'd have no sense by the end of Genesis that the story at the beginning is going to lead to a calendar of seven days. You might think that if people wanted to commemorate God's rest on the seventh day, they'd rest on the seventh day of every lunar month or the seventh day of every year.

It's only later in the Bible that there begins to be some sense that that story of creation could be linked to a calendar. So the creation story is part of the meaning of the Sabbath for Jews and for Christians too, but it's not clear that that is like the beginning of it. It's not clear that just because there was a creation story in which God rested on the seventh day that therefore people

I think it fills different needs and different purposes depending how it's used. I mean, not all societies that have observed the week have made it into a cycle of work and rest, but that is a primary thing that the seven-day week does for people is it prescribes a regular rhythm of taking off from work.
