Q. My son is having his Bar Mitzva birthday on Tisha Beav and we have a number of questions.
1) Does he get an aliya laTorah, on that like all other Bar Mitzva boys? (We are planing to do Be'H a big seuda on Shabbat Nachamu).
A. Poskim write that it is better to give the Bar Mitzva son an aliya on Mincha Tisha Beav. (Halichos Shlomo 15: 8, Nitei Gavriel 2: 60: 16, Kovetz Halochos 10: 26, Kaf Hachaim 554: 88, and others).
Horav Shlomo Miller Shlit'a opinion is similar.
