Great question. SCDNR will tell you a bunch of crap like "our rut lasts from August to Januarary". Bull. Here is what I have gathered to be our rut over the years. Give or take a week on my dates for strange weather.

Oct 1-20 = pre-rut, chasing does

Oct 21-Nov 10 = rut, with the peak being right on Halloween

Nov 11 - 25 = post rut

Nov 26 - Dec 15 = second rut, all does that didn't get tended first time around go back into heat, Dec 5 is the peak of the second rut.

This is strictly the data I've come up with for myself.
