On the mornings of Sukkot, Shacharit and Musaf follow the standard festival format. The lulav and etrog should be shaken.
The intermediate days of Sukkot, the weekdays, combine some features of festival days and normal weekdays to create wholly unique day.
The final two days of Sukkot are a totally separate holiday called Sh’mini Atzeret. Liturgy includes Yizkor and the prayer for rain.
Simḥat Torah means “the joy of Torah” and is the name for the day on which the annual cycle of Torah readings begins and ends.
