Halocho #1087 - Haircuts tomorrow

Lag B'Omer - the 33rd day of the Omer - will be on Sunday. No Tachanun is said on Sunday, and צִדְקָתְךָ צֶדֶק is not said on Shabbat at Mincha.

One may have haircuts on Friday (tomorrow) already, in honor of Shabbat.
All other customs of mourning are to be observed until the morning of Lag B'Omer.

Those who have the custom to mourn from Rosh Chodesh Iyar, resume the mourning customs after Lag B'Omer.

Note: Many Sefardim only stop the mourning on the 34th day of the Omer and don't allow haircuts on Friday.

Shabbat Shalom
