Tu B'Shevat (Also known as Tu BiShvat) is a Jewish observance also known as New Year of Trees. It is celebrated on the 15th day of the Hebrew month Shevat. Today, many Jewish communities promote ecological awareness on this day, planting trees in celebration. Meals on this day often consist of dried fruits and nuts. According to Orthodox Jewish belief, fruit is not considered Kosher until the tree is three years old. Any fruit produced in the third year on or after Tu Bishvat is considered Kosher and safe to eat.
