Q. I’m Askenaz but I joined a Sephardic congregation that keeps sefirah only until Lag Baomer. For the pupose of shaving for a job interview as in my previous question, could I have changed my minhag and kept the prohibitions this year from Rosh Chodesh Iyar until Shavuot? would I have needed Hatarat Nedarim?

A. Igrois Moishe (O.C. 1,159 and O.C. 2,95) maintains that as far as sefira customs is concerned, it is permissible to change from one minhag to another.

Horav Shlomo Miller Shlit”a advices if possible to maintain ones tradition, but if one does modify it would be better to do Hatoras Nedorim,
