About Yud Tet Kislev – The Rosh Hashanah of Chassidism
Yud Tet Kislev (the 19th of Kislev) is celebrated as the "New Year" of Chassidic teachings. On this day in 1798 (19 Kislev 5559), the founder of Chabad Chassidism,
Rabbi Schneur Zalman of Liadi (the Alter Rebbe), was released from imprisonment in Czarist Russia. His arrest was an attempt to suppress the spreading of Chassidic
philosophy; his miraculous liberation is seen as a victory for Jewish spiritual freedom and the dissemination of Torah and Chassidut.
Each year, Chassidim and many Jews worldwide mark this date with gatherings, increased Torah study, and acts of goodness and kindness. The special call 4X19RAV
combines "19" (for 19 Kislev) with the Hebrew word RAV which means "Rabbi".
