(Most of whom I'd wager learned about it from Michael Rood, as did I in 2000).
If you are not already familiar with the concept, the idea is that the appointed times which God gave to Israel to keep were also prophecy.
Likewise, there was a planetary alignment on the summer solstice of that same year which is also incomparable in history. Genesis tells us that one of the purposes of the heavenly bodies is to mark times and give signals.
We would therefore expect something significant to be evident in the heavens for a time as important as creation. E, 6000 years from 4001 BC, there was another rare planetary alignment.
It's hard to answer that with any confidence from these verses alone.
A few other key verses found in the OT and especially the NT shed light on how to understand the six-day work week prophetically: These passages establish what is called the "day-for-a-year" principle.
Or as Jesus said, he came to fulfill the Law because "not one jot or tittle would pass from the Law until " (Mt -18).
