Shacharis
After Shemoneh Esrei, the whole Hallel is recited, followed by Kaddish Shalem. For more on Hallel, see below, “Hosafos.”
Hallel is followed by Shir Shel Yom and Barchi Nafshi.
Krias Hatorah
Three Sifrei Torah are removed from the aron kodesh. From the first Sefer Torah, six aliyos are read in Parshas Mikeitz. (The sixth aliyah continues until the end of the parshah.) The second Sefer Torah is then placed next to the first one. This is followed by hagbah and gelilah of the first Sefer Torah.
From the second Sefer Torah, Uveyom hashabbos is read for the seventh aliyah (Bamidbar 28:9–15). The third Sefer Torah is then placed next to the second one, and Chatzi Kaddish is recited. This is followed by hagbah and gelilah of the second Sefer Torah.
From the third Sefer Torah, Bayom Hashishi is read for Maftir (Bamidbar 7:42–47). This is followed by hagbah and gelilah of the third Sefer Torah.
For the haftorah, Rani Vesimchi is read (Zecharyah 2:14–4:7). This is followed by the first and last possuk of the haftorah of Rosh Chodesh, as well as the first and last possuk of the haftorah of Machar Chodesh (I Shmuel 20:18, 20:42).
When saying the first and last possuk of the haftorah of Rosh Chodesh, say the pessukim of Ko amar Hashem (Yeshayahu 66:1), Vehayah midei chodesh (ibid. 66:23), Veyatz’u vera’u (ibid. 66:24), and again Vehayah midei chodesh (ibid. 66:23).
Musaf
Do not say Av Harachamim.
Say Atah Yatzarta (instead of the regular Tikanta Shabbos). See below, “Hosafos,” for the laws that apply if you said Tikanta Shabbos.
Rest of the Day
The Rebbe encouraged arranging farbrengens (in shul) on Rosh Chodesh.
During Minchah, omit Tzidkas’cha.
The Frierdiker Rebbe cites an “ancient custom” to study another possuk from the kapitel corresponding to one’s age each Rosh Chodesh, along with Rashi’s explanation (and additional commentaries). For Tehillim with Rashi, visit www.chabad.org/16222.
If there are less than twelve pesukim in your kapitel (or less than thirteen in a leap year), when you finish the kapitel, learn it a second time. If there are more than twelve (or thirteen) pesukim in your kapitel, study enough pesukim each Rosh Chodesh to finish the kapitel over the course of the year.
