How to use these dates. Rut timing is driven mainly by photoperiod, so these windows hold up well year to year. What moves is visible daylight activity — cold fronts, wind, and hunting pressure shift when deer move inside the window. Use the dates to pick your week, then the daily forecast to pick your morning. Always verify seasons with your state agency.
