11 Nissan
The term "11 Nissan" refers to the eleventh day of the Hebrew month of Nissan. In the Hebrew calendar, Nissan is the first month of the ecclesiastical year, occurring in the spring, typically corresponding to March-April in the Gregorian calendar. 11 Nissan is significant in some Jewish communities as the birthdate of Rabbi Menachem Mendel Schneerson, the seventh Rebbe of the Chabad-Lubavitch dynasty. This date is often commemorated with increased acts of charity, prayer, and learning, and is seen as an auspicious day for new beginnings and spiritual growth.
