R’ Tzvi Yaakov Stein: Halachos of Three Weeks


This Sunday, July 17th is the fast of Shiva Asar B’Tamuz. This year the 17th of Tamuz falls on Shabbos, as such, the fast is a taanis nidcheh, and it is postponed until Sunday. Someone who feels unwell should consult a Rav as the obligation to fast on a taanis nidcheh may be somewhat more lenient.

The following Halachos are only for the Three weeks. Nine days is more strict.


⁃ Haircuts are not allowed for men or for women.

⁃ Shaving and trimming beards are not allowed.

⁃ Electrolysis, waxing, etc. for women is allowed.

⁃ If one is going to take a loss then shaving/haircuts are allowed until the week of tisha bav.

⁃ Mustache that prevents you from eating can be cut even during the week of tisha bav.

⁃ Wigs can be cut if necessary.

⁃ Nails can be cut up until the week of tisha bav.

⁃ If tisha bav falls out on Shabbos then nails can be cut on Erev Shabbos.
