1. The Unique Joy of the 15th of Av
The reason we did not say Tachanon—supplicatory prayers—at Mincha—the afternoon service—is because today is the 15th day of Av, known as Tu B’Av. This is somewhat surprising, as the Gemara states that the Jewish people did not have days as joyous as the 15th of Av and Yom Kippur. While Yom Kippur’s greatness is clear—it is a day of selicha v’kaparah—forgiveness and atonement from Hashem for all our sins, making it a time of immense joy, the significance of Tu B’Av requires further exploration.2. Shidduchim and Family Joy on Tu B’Av
The Gemara describes how on Tu B’Av, young Jewish women would go out into the orchards, leading to many shidduchim—matches—taking place. Each group of women would call out different qualities: the wealthy would highlight their wealth, the beautiful their beauty, and others their virtues. The day was filled with happiness because there is no greater joy in a family than when they merit to see a child reach maturity and find a proper zivug—match. Anyone who has experienced the challenges of arranging a shidduch today can appreciate why this was such a celebrated occasion.3. The Symbolism of the Moon and Renewal
Another explanation for Tu B’Av’s significance relates to its timing: it falls on the 15th day of the month, when the moon is full. The Jewish people are compared to the levonah—moon—which waxes and wanes but always renews itself. Even during times of galus—exile—when things seem bleak and our light diminishes, we are destined for renewal and resurgence just like the moon regains its fullness. The 15th marks the peak of this cycle, symbolizing hope and rejuvenation for Am Yisrael.4. Celebrations on the Fifteenth: Pesach, Sukkot, and Beyond
Many significant celebrations in Judaism begin on the 15th day of their respective months: Pesach starts on the 15th of Nisan (with the korban Pesach brought on the 14th), Sukkot begins on the 15th of Tishrei. Yet Tu B’Av is considered by Chazal to be an even greater festival in one aspect. This is because it follows Tisha B’Av—a period marked by mourning and restrictions culminating in deep sorrow for our losses.5. From Mourning to Celebration: The Power of Contrast
The greatness of Tu B’Av is heightened by its placement after Tisha B’Av. Just as with the moon’s cycle, after reaching its lowest point it begins to grow again, so too does Am Yisrael move from mourning to celebration within Av. After days filled with difficulty and challenge—the first nine days culminating in Tisha B’Av—the arrival of Tu B’Av signals renewal, hope, and communal joy through shidduchim and other positive developments.6. The Deeper Meaning Behind Not Saying Tachanon
Not saying Tachanon on Tu B’Av carries deep meaning. It does not indicate a loss or omission in our prayers; rather, it reflects that Hashem grants us forgiveness without our needing to recite these supplications explicitly. When we omit Tachanon, it means that what we would have accomplished through those prayers has already been granted by Hashem Himself.7. How to Celebrate Tu B’Av Today
While some holidays have specific mitzvos or rituals attached to them, Tu B’Av does not have particular formal expressions in halacha today. Nevertheless, it remains important to mark this special day with joy—perhaps by listening to uplifting music or dancing (rikud)—and by taking note of its unique status as a time for celebration within Am Yisrael.
