Squirrel season opens here in mid-August and runs through February. Archery deer season starts mid-September through mid-January. Rifle deer season runs in October through mid-January. There is about 2 weeks in early March with nothing to hunt, but turkey season starts mid-March through mid May.
There are only about 12 weeks out of the year when there is nothing open to hunt. And technically I could hunt non-game animals such as coyote and hogs then. But 10 of those 12 weeks are in June, July, and August when it is 90-100 degrees.
I've never kept up with the days. I usually wait until things cool off and start hunting something in September and am in the woods at least once/week until May. During rifle deer season or early in turkey season I might be in the woods 2-3 days a week. So, I'm going to guess 50+ days now that I've retired.
But to be honest, at this point in my life killing something just isn't a huge priority. I just enjoy spending time outdoors.
