What is בה"ב? It stands for Monday, Thursday, Monday. The בעלי התוספות instituted 3 fast days after Pesach and Succos to atone for any sins that we did over the Yom Tov (we ate too much, socialized with the opposite sex improperly, etc.). Because we are not allowed to fast in Nisan we observe it in the beginning of Iyar. Nowadays, there are very few people who actually fast. However, some shuls do say selichos (for example where I daven we said selichos this morning) .
It will be interesting to hear what the readers know/do about בה"ב, and therefore I would like to ask the following questions of the readers:
1. Had you heard of בה"ב before reading this blog?
2. Do you fast or know of anyone who fasts?
3. Do you (or your shul) say slichos?
