Today’s ushpizin are Moshe Rabbeinu and the Mitteler Rebbe. For Hoshanos, the paragraph Adon hamoshia is said. The aliyos in today’s kriah are as follows: For Kohen, Uvayom hashlishi is read; for Levi, Uvayom harevi’i is read; for the third aliyah, Uvayom hachamishi is read; and for the fourth aliyah, Uvayom hashlishi and Uvayom harevi’i are read. In Musaf, insert the paragraphs Uvayom hashlishi... Uvayom harevi’i.
When lighting candles, only the berachah of Lehadlik Ner Shel Shabbos Kodesh is said. Before Minchah, say Pasach Eliyahu but omit Hodu.
On each day of Chol Hamoed, males over bar mitzvah drink a revi’is of wine to fulfill the mitzvah of simchas Yom Tov. When bentching, insert Yaaleh Viyavo and replace Magdil with Migdol. Additionally, say the harachaman for Sukkos. (See below, “Hosafos,” for the laws that apply if you forgot to say Yaaleh Viyavo.) When making a berachah acharonah mei’ein shalosh (e.g., Al Hamichyah), add the words vezachreinu letovah beyom chag hasukkos hazeh. However, if you forgot to add them, do not repeat the berachah.
