The opening as it read in 2005

Tu Bishvat (ט״ו בשבט ṭū bišḇāṭ ) is the Jewish holiday equivalent of Arbor Day — it is the new year for trees . This day was set aside in the Mishnah on which to bring fruit tithes . It is still celebrated in modern times. In the 1600s Land of Israel , Rabbi Yitzchak Luria of Safed and his disciples created a short seder , reminiscent of the seder that Jews observe on Pesach , that explores the holiday's Kabbalistic themes. It is customary on this holiday to eat different types of fruit. Traditionally, these types of fruit are: Fruits and nuts with hard, inedible exteriors and soft edible insides. Examples: oranges , bananas , walnuts , pistachios . Fruits and nuts with soft exteriors, but with a hard pit inside. Examples: dates , apricots , olives , persimmons Fruit that is eaten entire. In addition, kabbalistic tradition says that there is a fourth type of fruit, not of this world. The Jewish people gave trees a place of honor in the Jewish calendar. The scholars of the Mishna were greatly concerned with the date. Beit Hillel and Beit Shamai were divided on the issue of the date on which plants awaken from their winter hibernation and start to feed on the rains of the new year. "The first of Shvat is the arbor new year", said Beit Shamai. "The fifteenth," responded the Beit Hillel. (The Mishna of Rosh Hashana, A) It was the ruling of Beit Hillel that was finally adopted.1
