Jewish Mourning Customs Intensify During Three Weeks Between 17th of Tammuz and Tisha B'Av

The period known as the Three Weeks, from the 17th of Tammuz to the 9th of Av, marks a time of mourning in Jewish tradition commemorating the breach of Jerusalem's walls and the destruction of the First and Second Temples. During these days, customs of increasing mourning severity are observed, with variations between Ashkenazi and Sephardi communities.

Marriage ceremonies are generally prohibited from the 17th of Tammuz until after Tisha B'Av among Ashkenazim and some Sephardi groups, while most Sephardi communities avoid weddings from the beginning of Av until after Tisha B'Av. Engagements and conditions (tenaim) may be conducted throughout the period, but celebratory meals are restricted, especially after Rosh Chodesh Av, when only light refreshments without musical instruments are allowed.

Dancing and music are forbidden from the 17th of Tammuz onward, including recorded music, with exceptions for medical or psychological needs. Vocal singing is permitted but should be limited in joyful content after Rosh Chodesh Av. Haircuts are prohibited from the 17th of Tammuz among Ashkenazim and during the week of Tisha B'Av for most Sephardim, including shaving beards and mustaches, with allowances for religious obligations upon consultation.

Nail trimming is allowed until Rosh Chodesh Av, after which opinions differ, so it is recommended to complete this beforehand unless for a mitzvah or health reasons. Blessings such as Shehecheyanu are avoided on new fruits or garments during this time, except on Shabbat and Rosh Chodesh, with some stringency after Rosh Chodesh Av.

Additional customs include reciting the Tikkun Chatzot prayer after midday to mourn the Temple's destruction, except on Shabbat, Rosh Chodesh, and Erev Tisha B'Av. It is advised to limit travel, avoid dangerous activities, postpone non-urgent surgeries, and refrain from swimming or unnecessary flights during the Nine Days. The article concludes with a prayer expressing hope for a future time of joy and peace as foretold by the prophet Zechariah.
