According to R Moshe he allows haircuts (weddings etc) on the night of the 17th of Tammuz (night before fast) bshas hadchak. My wife is the one who gives me haircuts, financial reasons etc. She is not going to the Mikvah until the night of the 17th, so when she comes home, can she give me a haircut according to R’ Moshe? Would that be considered bshas hadchak, since she could not give me one earlier?
This year it surely doesn’t apply because the 17th is on Shabbos, therefore Motzei Shabbos is already the 18th of Tammuz, and R’ Moshe’s heter would not apply.
