I've heard a lot of people swear by halloween but I've seen the most rut activity the week of veterans days. Now with the extended archery season I think it'll be interesting to see what happens after veterans day. I can't really narrow it down to a day, but I'd suggest the week of veterans days or around then. Don't know what for time you get. Like others have said, everybody seems to experience different activity at different times in their areas. Good luck.
