Shemini Atzeret is the final day of festivities at the end of Sukkot. Shemini Atzeret literally means "the assembly of the eighth (day)." Rabbinic literature explains the holiday this way: G-d is like a host, who invites us as visitors for a limited time, but when the time comes for us to leave, He has enjoyed himself so much that He asks us to stay another day.
