Shabbat Shuvah
Begins at sundown on Friday, 25 September 2020 (8th of Tishrei, 5781)
Shabbat Shuvah (“Sabbath [of] Return” שבת שובה) refers to the Shabbat that occurs during the Ten Days of Repentance between Rosh Hashanah and Yom Kippur. Only one Shabbat can occur between these dates. This Shabbat is named after the first word of the Haftarah (Hosea 14:2-10) and literally means “Return!” It is perhaps a play on, but not to be confused with, the word Teshuvah (the word for repentance).
