11 Nissan
Yud Aleph Nissan, the 11th day of Nisan in the Hebrew calendar is the birthday of Rabbi Menachem Mendel Schneerson, the last leader of the Chabad dynasty of Hasidism until his passing in 1994, and is celebrated by his followers as a festival.
The day has been marked by public parades since 1992, when Rabbi Schneerson, was in 770 Eastern Parkway recovering from a stroke.
The first public recognition of Rabbi Schneerson's birthday was by his personal envoy to Washington DC, Rabbi Abraham Shemtov, who urged congresspersons to persuade President Jimmy Carter to declare the day Education and Sharing Day in his honor in 1978. The day has been declared Education and Sharing Day by all succeeding U.S. presidents.
The day is marked with many Mitzvah Tank parades around the world and with an annual official Tzivos Hashem rally, particularly in Crown Heights, Brooklyn.
