So there have been different answers given. Some people have speculated that it has to do maybe to do with the moon. That's, I think, a very unconvincing explanation to me because a quarter of a lunar cycle is not actually seven. Lunations are closer to 30 days than to 29 days. So you might have expected a moon-based fraction to be five or six. So I don't think that works.

Some people suggested that seven is a mnemonically useful number, that once you get to larger numbers, it becomes harder to remember all the constitutive elements. To me, that seems sort of plausible, but I don't think it would account for why so many different societies had seven and so many different societies didn't. So it really wasn't universal timekeeping system until relatively recently.

Traditional Christians, Jews, Muslims might say that seven is built into the fabric of the universe by the creation story. One might argue that something about the psychology or the physiology of the human body requires rest every seven days.

Again, all these things are plausible, not the moon one, but the other ones are all plausible, except they don't really account for why so many societies did just fine without seven. They might account for why seven has stuck. or why a couple of societies agreed on seven in the first place. But as you can tell by my tone of voice, I'm a little agnostic about the magic of seven.
