Yom Kippur is the day of Atonement. Sukkot, their harvest festival, follows it. All together the celebration lasts about a week. This happens late Septemberish (it shifts, as it follows the Jewish calendar, not the Gregorian calendar).
Most Jews do not believe in hell, they believe in Sheole, the land of the dead. They also believe in transmigration of souls (reincarnation) as the soul is eternal, and only it's physical casing changes. Earth is a testing ground to make your soul fit for reunion with God. I mentioned this on another thread.
Don't you and the Jews supposedly worship the same god Pianist? How can their god be trapped in a destroyed temple but still be the same god that is your all powerful deity?
I'm not trying to rag on your beliefs, I just don't understand. Your OP doesn't seem rational to me.
