Laws of The Three Weeks (Starting from the 17th of Tammuz)

  1. We do not hold weddings.
  2. We are not permitted to dance, play musical instruments, or listen to music.
  3. We do not shave or get haircuts. An adult may not give a haircut to a child. However, if you will incur financial loss if you do not shave, you are permitted to shave until the week in which Tisha B’Av occurs.
  4. We refrain from reciting the blessing of shehechiyanu. Therefore, we do not purchase or wear new garments or eat a new fruit for the first time. Until the first day of Av, you may purchase and wear new shoes, undergarments, socks, and shirts, since they do not require the blessing of shehechiyanu. On Shabbat, the above is permitted, and shehechiyanu may be recited.
