I'm with MWOSBORN.
I'll be on stand 30 minutes before legal shooting time and stay for at least 2 hours. Then I'll return about 2 hours before legal shooting time expires that afternoon. I hunt private land that is only very lightly hunted around it. If I had other hunters around me I'd stay an extra hour and go in an hour earlier.
After some fellow in CT tried to make a bunch of money on a "Moon Guide" more than 10 years ago, the concept was debunked by researchers using thousands of data points over a long period of time. (One research project was at Bent Creek Lodge(AL) -- 35,000 hunters over a 20 year period. Weather (especially temperature) was far more influential than moon phase.
My only interest in the moon is how cool moon shadows are walking in and out some days. I know lots of folks swear by moon phases though. I love to go out under a full moon because it adds to the beauty of the morning.
If that adds to the excitement, anticipation, and confidence of the hunter that's great. My best hunting buddy notes the position and brightness of the moon but doesn't plan his hunts accordingly he is just more or less optimistic on during some moon phases than others.
