Shemini Atzeret & Simchat Torah 2024. Images (from flash90) were not captured on the holiday. Shemini atzeret, literally the gathering of the eighth, appears, on the surface, to be the eighth day (and ninth day outside of israel) of sukkot.

The seven days of sukkot —celebrated by dwelling in the sukkah, taking the four kinds, and rejoicing. On tishri 22, the day after the seventh day of sukkot, is the holiday shemini atzeret.
