Couple comments to frame the discussion. We all heard that a cold weather snap, moon phase or other factors can trigger the rut. Answer is yes and no. Cold weather can increase rutting activity, but the timing of the rut is not impacted itself. Moon phase may cause an increase in activity but does not dictate the timing of the rut.
Fawns (the bulk of) are born within a small timeframe to give them the maximum advantage of survival. That trigger is consistent year to year. Photo period. Just like the elk the deer schedule is driven off the daylight/dark % of the day. In the west mid to late November will always be the peak of the rut year after year.
