An annual new year for trees was established by Talmudic rabbis so that Jews could calculate the age of trees and know when they could be harvested. This tree birthday is called Tu (15th day) B'Shvat (in the Hebrew month of Shvat). This year Tu B'Shvat begins at sunset February 7, 2012 and ends at nightfall February 8, 2012.
Jews today celebrate the festival of Tu B'Shvat in a variety of ways, such as learning about the environment, planting trees in Israel, and serving dishes containing fruit and grains mentioned in the Bible either for a regular meal or for a Tu B'Shvat Seder ceremony. You can celebrate Tu B'Shvat this year with these kosher Tu B'Shvat recipes.
And this Tu B'Shvat menu is designed to include the seven species (shivat haminim): wheat, barley, grapes, fig, pomegranate, olive and date.
