I agree with the above. Just like everything else it just depends. Some people hunt the mornings, take a nap, and go back out for the dusk hunt. Others will sit all day or go in a bit late to make sure they are on stand for noon and 1 o clock and they swear by it. For me, early archery season has been better in the mornings because it's coming off the cool night but the deer movement will also pick up right at dark. During the rut I would suggest being on stand whenever it seems good. Who knows when that big buck will get on his feet to run a hot doe near by. Once I start my late season Doe hunting (second week of December), I'll hunt almost all afternoons. The deer move better and I don't have to freeze right at sun up. I will also rely on cameras to let me know if a certain deer I am targeting is on his feet during certain times. Also another thing that is over looked is the moon phase. I constantly check that to see what they should be doing and it generally gives a picture of what's going on.
