I don't let the moon phases affect my hunting. I'm going to be out there anyway, full moon or not. There may be a little less morning movement on a full overhead moon, but I have killed some pretty decent bucks from 7 a.m. to 9 a.m. during a full overhead moon, and not during the rut. As for finding out when the moon will be overhead, just google it. You can easily find out on the net.
