"This guide for Shemini Atzeret is focused on those who live in the Diaspora. In Israel, where Shemini Atzeret and Simchat Torah are compacted into one day, all the practices of Shemini Atzeret and Simchat Torah (see Simchat Torah Guide) are observed on the same day." (source)
"Even though we were following the directions, we got farblondjet and ended up in Shemini Atzeret."
