Dates are one of the simanim for Rosh Hashana, the Jewish New Year.
Here’s what one says on the siman (symbol) of the date:
May it be your will, LORD our God and God of our fathers,
that those who hate us be ended (yitamu – from tamar, dates in Aramaic)
Would you go on a date with a girl named Tamar? Tamar is the Hebrew word for date, so you can play with words and come up with some funny phrases.
