Most units of time are based on nature. A day is one rotation of the Earth. A month is the moon’s orbit. A year is the Earth’s path around the sun.
But a week? There’s no natural explanation for it.
Well, given that a moon cycle is about 28 days long, each quarter of that is 7 days. Before we had electric lights at night, most people were very aware of the moon phase.
I feel like I’m missing a reference here, but are you ok?
