Tu b'Av is a relatively obscure Jewish holiday that falls on the fifteenth day of the month of Av (sundown Sunday, July 25 to sundown Monday, July 26 this year).
The fifteenth day of each month on the Hebrew calendar falls on a full moon, and the holiday was observed as a sort of fertility festival during the period of the Second Temple. After the destruction of the Second Temple, it was forgotten for the most part in the Diaspora, only to be revived in modern times as a Jewish alternative to Valentine's Day.

From Les Feuilles D'Automne
Child, were I king, I'd yield my royal rule,
My chariot, sceptre, vassal-service due,
My crown, my porphyry-basined waters cool,
My fleets, whereto the sea is but a pool,
For a glance from you!
Love, were I God, the earth and its heaving airs,
Angels, the demons abject under me,
Vast chaos with its teeming womby lairs,
Time, space, all would I give--aye, upper spheres,
For a kiss from thee!
