On average it takes 161 Jewish months to become Bar Mitzva. 13 x 12 = 156 + 5 extra Adars.

  • That'd be, I suppose, both the mode and the ceiling of the average (mean), but obviously not the exact average (up arrow from me anyway :-) ). – msh210 Jan 7 '11 at 5:23
  • @msh210 We deal in integers around here. This isn't the first time someone's shoehorned an answer into this series using floor or ceiling. How many days, for example, are in a month? – Isaac Moses Jan 7 '11 at 19:43
  • @Gershon, nice find! – Isaac Moses Jan 7 '11 at 19:43
  • @R'IM, I wasn't disputing or even frowning upon the answer (it was a nice find), but merely pointing out the math in case someone didn't realize. – msh210 Jan 7 '11 at 19:59

R'u was 161 was Avraham was born. (Source: Rashi to B'reshis 19:20.)
