eruv Tu b’AV (fifteenth of the Hebrew month of Av)
This evening begins the lesser known Jewish holiday of Tu b’Av. Most of us are familiar with the 9th of Av, that occurred last week, commemorating the destruction of both the first and second Temples. Contrary to the mournful tone of Tish b”Av, the holiday of Tu b’Av (15th of Av) is a joyous holiday, a welcome change to the mournful Three Weeks that led up to Tish b’Av.
What does the holiday of Tu b’Av commemorate? According to some sources, all of the firewood necessary for the offerings of the new year was gathered by this day. Additionally, this day is when the men courted the women, in an outside gathering. Many Jews today pray for shidduchim (a marriage arrangement) on this particular day, because the day is considered auspicious to receive a favorable reply from H’Shem.
