what is bar Mivah?! what if they didn't have it at the age of 13?! is it still a must for them bcz they are 13?מדינת ישׂראל;438375 said:At the age of 13, you become a 'man' or 'women' when it comes to complying with all laws of the Torah.
Therefore, when a Jewish women or man at 13 has a Bar-Mitvah or Bat-Mitzvah they are no longer kids, and they are now responsible to follow the laws of G-d.
So the awnser is... at 13.
