The day has been marked by public parades and sharing with fellows since 1992, when the Rebbe, Rabbi Schneerson, was in 770 Eastern Parkway recovering from a stroke.[1]

The first public recognition of Rabbi Schneerson's birthday was by his personal envoy to Washington DC, Abraham Shemtov, who urged friendly congressmen to persuade Jimmy Carter to declare the day to be Education and Sharing Day in his honor, in 1978.[2] 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.[3]
