Peak rut dates in Pennsylvania.
Pennsylvania has the most rigorously documented rut in North America — peak conception lands Nov 13–15 statewide, year after year.
Rut phases by zone

What drives the rut here
Pennsylvania's rut is the most studied in the country thanks to a decade-long Game Commission fetal-rate study spanning 6,000+ does collected from 2000–2007. Peak conception clusters tightly between November 13 and 15 across nearly every Wildlife Management Unit. Year-to-year variation is small — photoperiod, not weather, dictates timing. The PGC's published median conception dates remain the gold standard for predicting Pennsylvania rut activity.
