Fasting 3 fasts.


There is a somewhat famous minhag for a child to fast the three fasts preceding His/Her Bar/Bas Mitzvah.

Is there any halachic source for doing this, or is it an unnecessary adopted custom?

Why should this post be closed?

You have presented a false dichotomy. It could be there is no halachic source for it and it is still a necessary adopted custom. A family or communal custom can be binding on you even if it wasn't documented by a European rabbi a few hundred years ago. ‭AA​ ‭ about 1 month ago

According to, there doesn't seem to be any source for this custom.



Chabad labels this a “persistent myth.”
