Just relying on published work on rut timing that has been done for a very long time. It fits the anecdotal evidence you all are describing.
Exact timing shifts every year based on the lunar cycle and some weather. To attach exact calendar dates to the rut puts you at odds with deer from the areas they were moved from, the deer that were there, and the rest of the free world. But do carry on.
I am certain finding all sorts of stuff that agrees with you will be easy, but find the stuff with some peer review.
