Shabbat Parshat Nitzavim-Vayelech, 25 Elul / Sept. 27 and 28
● Although we do not bless the new month on this Shabbat, it is the Chabad custom to observe all of the customs of a regular Shabbat Mevorchim, specifically to recite the entire book of Tehillim and participate in a Chassidic Farbrengen. We observe these customs because there is a tradition from the Ba’al Shem Tov that G-d Himself blesses the month of Tishrei rather than the Jewish people who bless the other new months.
● Av HaRachamim is recited before Musaf.
● Tzidkat’cha is recited at Shabbat Mincha.
● See here for several connections between this week’s Torah portions and Rosh Hashanah.
