Tu BiShvat is a minor festival that takes place on the 15th day of the Hebrew month of Shvat, with the name itself referring to the date. It originates in the Mishnah (the first part of the Talmud, also known as the Oral Torah) and was an agricultural holiday in the Biblical Land of Israel.
Many communities celebrate it today by honoring the Earth, planting trees, and eating the Seven Species of Israel (wheat, barley, grapes, figs, pomegranates, olives, and dates) along with other fruits and nuts.

The New Year of the Trees
In Israel, Tu BiShvat is commonly a day for planting trees and celebrating nature, particularly the special bounty of the Land of Israel.
In Biblical times, Tu BiShvat marked a point between growing seasons and the start of a new agricultural year. It was used as a sort of "birthday" for all the trees in the Land of Israel in order to keep track of their age, which was important for calculating fruit bearing cycles as well as keeping track of contributing crops to the Temple and to the poor.
Today, the idea of a tree's "birthday" is less important from a practical standpoint, but the holiday's strong association with trees remains. Modern Jewish communities connect with the "New Year of the Trees" by planting trees around this time, particularly in the Land of Israel, and also often extend the theme of the holiday to honoring all nature.
It's common to use Tu BiShvat as an opportunity to participate in, donate to, and spread awareness of environmental causes and to honor the Earth.
