The Origin of the Seven-Day Week

So many of our timekeeping systems are based on traditions, such as the number sixty for our minutes that supposedly came from the Sumerians, twelves were used by the Egyptians, and so on. Others are straightforward astronomically, such as year, month and day. But a week?

Someone wrote that a week is a quarter of a lunar phase, but that does not set well because one can see the phases progressing night to night. Sometimes folks changed number of days in a week, but people seem hardwired to keeping the seven days.

There are also claims that the seven-day week originated with the Babylonians, but there are indications that it was used in the Bible long before then. Secularists reject the truth of the Bible and bristle when the six days of creation and the one day of rest are mentioned. (Exodus 20:11 reaffirms this.) God rested, but he is God and would not get tired. For that matter, he did not need to take six days. What's going on?

People were specially created, and God cares for us in many ways. He made the week for our sakes!

What does the secular community think? Many secular historians have (somewhat superficially) attempted to explain the origin of our seven-day week in various manners, all without using the Bible as a starting point. But the most common explanation is that it originated with the ancient Babylonians (around sixth century BC).

Moreover, we consistently see the significance (and the symbolism) of the seven-week model throughout the Bible. Particularly, when God orchestrated the global flood events during the account of Noah, He did it in terms of seven-day week cycles, as seen in Genesis 7–8.
