Thursday morning: Shacharis of Yom Tov (some congregations add the appropriate Yotzros as found in the Machzor), Shemoneh Esreh of Shalosh Regalim followed by whole Hallel. The Chazzan then recites Kaddish Tiskabbel. We read Megillas Ruth, preferably from a klaf, a scroll. [Most are accustomed not to say the beracha Al Mikra Megilla, see Shulchan Aruch HaRav. The Taz and the Magen Avraham, however, rule otherwise – that one does recite the blessing – but all agree that we do it only for a scroll.]
We remove two Sifrei Torah from the Ark and say the 13 Middos. We call five aliyos to the first Sefer Torah. We read in Parashas Re’eh (Devarim 15:19-16:17) from “Kol Habechor” until “asher nasan lach.” We then take the second Torah scroll, place it on the bimah next to the first scroll and recite half-Kaddish. The Maftir is read in the second Sefer in Parashas Pinchas (Bamidbar 28:26-31) from “U’veyom Habikkurim” until “Ve’niskeihem.” The Haftara is in Chabakkuk (2:20-3:19). The Maftir recites the first two verses, inserts the piyyut Yetziv Pisgam, and concludes the Haftara.
Yizkor: It is customary to make an appeal for charity before we say Yizkor for the departed souls and in the text we say “Ba’avur she’ani nosein tzedaka” – Due to my giving to charity. We say Ashrei (no Kah Keili), Yehallelu, Mizmor LeDavid etc. and return the Sifrei Torah to the Ark.
Musaf: Chazzan recites half-Kaddish, then all say the Shalosh Regalim Shemoneh Esreh. In the Chazzan’s repetition the Kohanim go up to duchan. Ein K’Elokeinu, Aleinu, Shir Shel Yom and respective Kaddish recitations. (Nusach Sefarad say Shir Shel Yom after Hallel.)
Mincha: Ashrei, U’va LeTziyyon, half-Kaddish, usual Shalosh Regalim Shemoneh Esreh, Kaddish Tiskabbel at the conclusion of Chazzan’s repetition, Aleinu, Kaddish Yasom.
Maariv: usual Tefilla, Ata Chonanta in the Shemoneh Esreh. Kaddish Tiskabbel, Havdala, Borei Pri Hagafen, Hamavdil (no spices, no flame), Aleinu, Kaddish Yasom. Yom Tov concludes, 45 min. – 8:53 p.m. E.D.T. NYC.; 60 min. – 9:08 p.m. N.Y.C. E.D.T.; 72 min. 9:20 p.m. N.Y.C. E.D.T.
Isru Chag: Tomorrow is Isru Chag we do not say Tachanun nor do we eulogize, nor do we fast. (Shulchan Aruch Horav, O.C. 494:sk19)
The following chapters of Tehillim are being recited by many congregations and Yeshivos for our brothers and sisters in Eretz Yisrael: Chapter 83, 130, 142. – Y.K.
