When specifying years of the Hebrew calendar in the present millennium, we omit the thousands (which is presently 5, ה). For example, the Hebrew year 5782 is written as 782 (תשפ״ב) rather than 5782 (ה׳תשפ״ב).

Tu B’Av (Hebrew: ט״ו באב, the fifteenth of the month Av) is a minor Jewish holiday. In modern-day Israel, it is celebrated as a holiday of love (חג האהבה Ḥag HaAhava).
