Tu B'ShvatFebruary 10, 2017
When you come to the land and you plant any tree, you shall treat its fruit as forbidden; for three years it will be forbidden and not eaten. In the fourth year, all of its fruit shall be sanctified to praise the Lord. In the fifth year, you may eat its fruit. ~ Leviticus 19:23-25
Tu B'Shevat is sort of a Jewish Arbor Day, a New Years for Trees.
In the Hebrew calendar, Tu B'Shvat is the date for calculating the age of a fruit-bearing tree.
The Torah states that fruit from trees which were grown in the land of Israel may not be eaten during the first three years (called orlah); the fourth year's fruit is for God, and after that, the fruit can be eaten. Each tree is considered to have aged one year as of Tu B'Shvat, no matter when in the year it was planted.
The 15th day of the month of Shvat marks the beginning of the "new year" for trees. It is customary to plant trees and partake of the fruits of the land of Israel to mark the occasion.
