They're ripe, now....and WE know they're sweet, to us, after the first frost. I think deer will eat them ANY time they hit the ground or they can reach them.
I have three know persimmon trees in my hunting areas. I'll be hunting near them as soon as I get a good wind and I wanna go doe hunting (that's where these trees are.....doe laden areas).
Good luck Frank.....and give me a call when you can shoot up and do some hunting.

I'll sit you near a persimmon tree! But wait until we get a wind without an "N" in it.
