My Brother in Law is getting married 2 days after Pesach.
My minhag is not to listen to music the whole Sefira with the exception of Lag BaOmer.
Am I allowed to attend the AND dance by the Chasuna?
First of all Mazal Tov. May they be zoche to biuld a bayis neeman b’yisroel.
You may go to the chasuna, and you can dance also. The reason is since the choson and kallah are allowed to get married then, all those participating are allowed to be there alos.
