You may be asking yourself: what in the world is Tu B'shvat? We admit, it is certainly one of the more obscure Jewish holidays, but its focus on celebrating the bounty of the earth and conservation seemed a natural fit with our building's green restoration. And there is never a bad reason for a free festival! We see this as the winter counterpart to our fabulous Egg Rolls and Egg Creams Festival, which we host every June in celebration of the Jewish and Chinese cultures that share Eldridge Street.
The name Tu B'shvat is actually the date of the holiday, the 15th of the month of S'hvat. The holiday is first mentioned in the Mishna, where the ancient rabbis have a little throwdown over the date. They discuss the four "New Years" in the Jewish calendar (I wonder what they used for the ball drop in ancient Babylon?):
The first of Nisan - new year for kings and festivals - The first of Elul - new year for animal tithes. Rabbi Elazar and Rabbi Shimon say: the first of Tishrei. - The first of Tishrei- new year for calculation of the calendar, sabbatical years and jubilees, for planting and sowing - The first of Shevat - new year for trees, according to the school of Shamai; The school of Hillel say: the fifteenth of Shevat (Rosh Hashana:2a)
