Tu Bishvat usually arrives quietly. It is not marked by prohibitions or ceremonies, nor by the drama of a festival. And yet, hidden behind its modest customs lies a complex legal story—one that follows trees from planting to fruit, rain from season to season, and people from obligation to gratitude. What begins as a technical date in the halachic calendar unfolds into a framework that governs how years are counted, how sanctity is measured, and how enjoyment itself is disciplined.
To understand Tu Bishvat, then, is to follow the law’s careful attention to growth, time, and human responsibility—and to see how custom emerges naturally from halacha, rather than standing apart from it.
Tu Bishvat: The Fifteenth of Shevat
The fifteenth of Shevat—Tu Bishvat—is the “New Year for Trees,” in accordance with the view of Beit Hillel, whose rulings are accepted as halachic law in all cases. In Jewish law, fruit-bearing trees have both an age and an annual classification.
Knowing the age of a tree is necessary because of the laws of orlah: the prohibition against deriving any benefit from the fruit of a tree during its first three years. Knowing the annual classification of its fruit is required because of the laws of terumot and ma’asrot (tithes), which must be separated from each year’s produce independently. Certain tithes apply only in particular years, so it is essential to determine to which year a given fruit belongs.
A “year” for fruit trees is determined by the rainfall that nourishes the fruit. Once most of the year’s rain has fallen—meaning the bulk of the rainy season has passed—the annual cycle of the trees is considered complete. Fruit that has set (chanatah, the stage when the blossom falls and the young fruit appears) before that point belongs to one year; fruit that sets afterward belongs to the following year.
Beit Shammai and Beit Hillel disagreed about the precise date on which “most of the year’s rains” are considered complete. According to Beit Shammai, it is the first of Shevat; according to Beit Hillel, the fifteenth of Shevat. Although the rainy season follows the solar cycle while the Jewish months are primarily lunar, the fixed synchronization of the Jewish calendar largely obscures this difference.
In any event, the dates established by Beit Shammai and Beit Hillel are formal legal benchmarks and do not account for exceptional weather patterns.
How Old Are You?
With respect to orlah, a tree undergoes an interesting legal progression. It begins as a sapling that is not yet halachically classified as a “tree,” and therefore its “New Year” is the first of Tishrei, not Tu Bishvat.
If one plants a tree between the first of Tishrei and the fifteenth of Av, then when the next first of Tishrei arrives, the sapling is considered one year old—even if it is, in reality, only forty-five days old. This is because Jewish law considers “thirty days in a year” sufficient to count as a full year, and after roughly two weeks the sapling has already taken root in the soil, allowing its years to be counted.
On the ensuing first of Tishrei, the tree is considered two years old. One might then expect that on the proceeding first of Tishrei it would reach the age of three and complete its orlah period. However, by that stage the sapling has become a full-fledged tree, whose New Year is Tu Bishvat. As a result, its third year does not end until Tu Bishvat following its third first of Tishrei.
If we summarize this in the form of a riddle: what is the maximum length of time during which a tree can be considered orlah? The answer is simple: a tree planted on the sixteenth of Av. It misses the opportunity to count the remaining days of that year as its first orlah year and must wait until the following first of Tishrei—not the upcoming one—to begin counting. In this way, its orlah period can extend to three and a half years. For example, from the sixteenth of Av 5778 until Tu Bishvat 5782.
Where Is Your Rain?
In addition to a tree’s age, one must determine the annual classification of its fruit. Produce is classified by year for two reasons:
-
Terumot and ma’asrot must be separated only from produce of the same year; produce from different years may not be mixed.
-
The type of tithe changes from year to year.
From each year’s produce, one separates terumah, which is given to the priests (kohanim) and may be eaten only by them, and only in a state of ritual purity. After terumah, one separates ma‘aser rishon, which is given to the Levites. This tithe is not sacred and may be eaten by anyone.
After these, an additional tithe is separated, whose identity depends on the year. Once the Jewish people entered the Land of Israel, conquered it, and divided it among the tribes, they began counting shemittah cycles for agricultural produce: six years of cultivation followed by a seventh sabbatical year. Even today, thousands of years later—although many of the laws derived from this cycle are no longer practiced—we continue to count these cycles in order to determine shemittah years and the applicable tithes.
Terumah and ma’aser rishon apply every year except the sabbatical year. The additional tithe is given to the poor in some years, while in others it is ma’aser sheni, which must be eaten in Jerusalem in a state of purity. Since most people are unable to consume fresh produce in Jerusalem, the Torah provides for redeeming ma‘aser sheni onto money, which is later used to purchase food in Jerusalem. Today, since we cannot observe these laws fully, we symbolically redeem the sanctity of the fruit onto a nominal sum of money, which is then not used.
In the first, second, fourth, and fifth years of the shemittah cycle, ma‘aser sheni applies; in the third and sixth years, the additional tithe is given to the poor. Tu Bishvat marks the beginning of a new year for this purpose. Fruit that sets before Tu Bishvat belongs to the previous year (since shemittah and tithe years begin on the first of Tishrei), while fruit that sets from Tu Bishvat onward belongs to the current year.
This rule applies uniquely to trees, based on the assumption that fruit relies on rainfall only until the chanatah stage; afterward, it ripens through the tree’s own vitality. Vegetables, by contrast, continue to rely on rainfall until they are harvested, so their tithe year is determined by the time of picking. Vegetables harvested before the first of Tishrei belong to one year; those harvested afterward belong to the next.
An Annual Fruit Celebration
As we can see, Tu Bishvat is, in essence, a purely formal halachic date, with no inherent festive character. A parallel example would be the first of Elul according to some early authorities, which served as the “New Year for animal tithes.” Just as agricultural produce is tithed annually, so too livestock: animals born within a given year are counted, and every tenth animal is consecrated and brought as a sacrifice, whose meat is eaten in Jerusalem under strict conditions.
In practice, however, the New Year for animal tithes is the first of Tishrei—not the first of Elul—and the first of Tishrei is already a festival regardless. As a result, this halachic designation receives no special observance.
Nevertheless, Jewish custom has embraced Tu Bishvat as a day of modest celebration. Public fasts are not declared on this day, and Tachanun—the supplicatory prayer recited with bowed head after the Amidah—is omitted. Homiletic literature offers various explanations for this custom; we will suffice with one particularly intriguing reason.
The Jerusalem Talmud records a teaching in the name of Rabbi Chizkiyah:
“In the future, a person will be called to account for everything his eyes saw and he did not eat.”
In other words, a person is expected to take pleasure in the blessings of this world. Of course, one must do so with balance and restraint, avoiding overindulgence—but complete abstinence is also improper. One must, as it were, abstain from abstinence.
The Talmud relates that the sage Rabbi Elazar heard this teaching and took it seriously. Once a year, he would seek out an especially fine variety of fruit and eat it, so that he could later say before the Heavenly Court: I did enjoy.
Thus, once a year, it is fitting to partake of fine fruit. When is the most appropriate time? Tu Bishvat. Pleasant customs are best anchored in halacha, and since Tu Bishvat is legally tied to the fruit of trees, it is the ideal occasion to enjoy new fruit.
“Who Has Kept Us Alive… to This Moment”
The Sages instituted many blessings to infuse spiritual meaning into human experience. Beyond blessings tied to specific events, they established a general blessing for good occurrences: “Blessed are You… who has kept us alive, sustained us, and brought us to this moment” (Shehecheyanu).
Certain times of the year—such as festivals and Yom Kippur—are inherently joyous, and Shehecheyanu is recited upon their arrival. Likewise, certain events are explicitly identified as occasions for this blessing, such as purchasing a new home, a new garment, or encountering new fruit.
Originally, the blessing was recited upon merely seeing new fruit, but in practice, it is recited only when eating it. Apparently, the joy of seeing new growth is not universally felt strongly enough to warrant a blessing, so the custom developed to recite Shehecheyanu only upon consumption.
Strictly speaking, reciting Shehecheyanu over new fruit is not an absolute obligation but a commendable practice. Nevertheless, Rabbi Yechiel Michel Epstein—author of Aruch HaShulchan—notes that common practice treats it as obligatory, and one should therefore be careful to observe it.
Customs vary regarding the order of blessings. Every act of eating requires a berachah rishonah (a preliminary blessing), and for tree fruit this is “Borei peri ha’etz.” A new fruit thus requires two blessings: Shehecheyanu and Borei peri ha’etz. Which comes first?
Normally, speaking between a blessing and eating is forbidden, as it constitutes an interruption that can render the blessing invalid. However, speech that is necessary for the act of eating does not count as an interruption.
For this reason, many recite Borei peri ha’etz first, followed by Shehecheyanu, immediately before eating. Since Shehecheyanu pertains directly to the act of eating, it is not considered an interruption. This is the ruling of Rabbi Yisrael Yaakov Chagiz (17th century), author of Halachot Ketanot.
The Mishnah Berurah, however, rules the opposite order: Shehecheyanu first, followed by Borei peri ha’etz. Since Shehecheyanu was originally instituted even for seeing the fruit, it is preferable, in his view, to place the eating-blessing immediately adjacent to consumption.
Some follow one view, some the other. As usual, some attempt to satisfy all opinions by creative solutions—for example, eating an old fruit (which does not require Shehecheyanu) alongside the new one, blessing Borei peri ha’etz on the former and Shehecheyanu on the latter. Yet this can generate new complications.
When multiple fruits are present, the halacha requires one to bless first on the fruit one prefers most. If the new fruit is the more beloved, then Borei peri ha’etz should be recited over it—bringing us back to the original dilemma.
Attempts to resolve this by removing the new fruit from sight may fail, since a blessing on one fruit may not cover another that is not present. A partial solution may be to leave the fruit present but covered, though even this raises questions.
In the end, it seems preferable to adopt a consistent practice following one of the two well-established halachic approaches.
Conclusion
Tu Bishvat thus emerges as more than a symbolic celebration of nature. It is a moment in which halacha, agricultural reality, and human experience converge: the discipline of law shapes custom, and custom, in turn, gives the law a human face. Through the careful counting of years, the measured enjoyment of fruit, and the blessings that frame that enjoyment, the day reminds us that Jewish life seeks not withdrawal from the world, but sanctified engagement with it—attentive to time, to growth, and to the simple, serious joy of God’s blessings.
