Tu b'Av ט״ו באב
The truth is that love is the highest goal to which man can aspire.
- Victor Frankl
Jewish Holiday of Love
Literally the '15th day of Av', Tu b'Av is both an ancient and modern holiday. Originally a post-biblical day of joy, it served as a matchmaking day for unmarried women in the Second Temple period but went almost unnoticed for many centuries until it has been rejuvenated in recent decades. If you like, Tu b'Av is the Jewish version of Valentine's Day.
