About the festival
Tu bi-Shevat, the fifteenth day of the month of Shevat, is known as the "New
Year for Trees." This date determines the end of the "fiscal year"
for trees for tithing purposes; in the time of the Temple, fruit that ripened
before the fifteenth of Shevat was taxed for the previous year, fruit that ripened
later, for the following year.
|In Hebrew: Rosh
Hashanah la'Ilanot. The Mishnah mentions four different new years during
the Jewish cylical year, the new year for the trees (for purposes of tithes
and similar laws) being one. The School of Hillel reckoned the new year
for the trees from the 15th of Shevat, while the School of Shammai designated
the 1st of Shevat. 
In the community
Tu bi-Shevat actually marks the early beginnings of the spring season in Israel,
at the time of the almond tree blossom. Through the Keren Kayemet l'Yisrael
(Jewish National Fund) organization which is responsible for planting trees
in Israel, Israeli school children plant trees on this day. In recent years,
Tu bi-Shevat is becoming a day of environmental awareness in Israel. Jewish
children abroad purchase Jewish National Fund certificates for the planting
of trees in Israel, sometimes in honor or in memory of friends and relatives.
|The mystics of Safed saw profound esoteric
meaning in the verse: "For man is like the tree of the field." 
In some Sephardi communities the men remain awake all night studying Biblical,
Talmudic and Kabbalistic sources relating to the fruits of the land, stopping
every so often to eat a different kind of fruit. In some communities a Tu bi-Shevat
"seder" is held, a custom which emerged under the influence
of the 17th-century Kabbalists of Safed.Modeled on the Passover seder,
this ceremonial meal involves eating fruits and nuts and drinking four cups
of wine with varying proportions of red and white wine, representing the shifting
of the seasons. The seder also includes readings on trees and fruit
from a range of Jewish literary sources.
|One of the earliest published texts for
such a Tu bi-Shevat seder Peri Etz Hadar (Fruit of the Citrus
Tree) was published in Salonika in 1753.
Many Jewish communities observe Tu bi-Shevat by eating fifteen different kinds
of fruit, especially the new fruits of the season. A popular custom is to eat
the five fruits mentioned in the biblical description of the land of Israel
- grapes, pomegranates, figs, dates, olives, and bokser (St. John's
bread) which is the fruit of the carob trees.
|"...a land of wheat and barley, of vines,
grapes, figs, and pomegranates, a land of olive trees and honey [dates]."
