From the Rav’s Desk: When do the three week regulations begin, the night of the 17th or the next day?

  1. Question: [Tuesday, 15th Tamuz 5783]

There is a concert scheduled to take place this Wednesday night which is the 17th of Tamuz. May I go to the concert? My basic question is do the three-week restrictions begin to apply already on the night of the 17th of Tamuz or do they only begin the next morning when the fast begins?


The laws of Aveilus begin from the night of the 17th of Tammuz. Accordingly, you may not attend such a concert. The same applies regarding all other laws of the three weeks, that they begin starting from sunset on the 16th of Tamuz. Thus, you are to get a haircut prior to this time, and are to no longer recite the blessing of Shehechiyanu, listen to music, or get a haircut, starting from this time.


Being that we do not begin fasting until the morning of the 17th of Tamuz, the question is raised as to whether mourning restrictions of the three weeks only begins then or begins from the night before by the start of the actual date of the 17th. Practically, the Chida concludes that all of the mourning restrictions begin from the night of the 17th, and not from the next day, as the time of the start of the fast has nothing to do with the mourning restrictions, and it is a mere leniency that we delay the fast until the morning being that it is difficult to fast a full day. So is also the implied ruling from all of the Poskim and Shulchan Aruch who never qualify that the three-week laws only begin from the morning and supplying it they begin the night before and it is literally three weeks. Rav Moshe Feinstein however in his responses took a more lenient approach [without mentioning the opinion of the Chida] and permits in a time of need and in certain circumstances for a person to be lenient in this matter until the morning of the 17th. Practically, the main approach follows the ruling of the Chida.
