Lag B’Omer this years falls on
Sunday, May 2nd. Am I allowed
to get a haircut on Friday, April 30th erev Shabbos?
[Remo”h in Shulchan Aruch, Orach Chaim 493:2]
This is also the view of Maharika”sh (Oholei Yaakov 98), quoted in Yabi’a Omer, (vol. 6, Orach Chaim 47). However, Kaf Hachaim (O.C. 493: note 32) writes that those who follow the opinion of the Mechaber and do not have a haircut until day 34 of the Omer, may not take a haircut until Monday (this year).
