Is there a Jewish holiday that highlights love?

Answered by
Rabbi Victor S. Appell

A little-known holiday is Tu B'Av (the fifteenth of Av – which falls mid to late summer). Following the reflective nature of Tishah B'Av  and preceding Elul, a month of preparation for the High Holidays, Tu B'Av is a day marked by dancing and courtship. Ancient traditions note that on this day, young women, dressed in white, went out into the fields to dance and were followed by young men.
