Halocho #510 - When does the younger boy become Bar Mitzva first?

Thirteen years ago - 1997 - תשנ"ז was a leap year - with an Adar-1 and an Adar-2

Boys born in both these months become Bar Mitzva next month - in Adar.

As a result, a boy born on the first day of Adar-2 5757 will become Bar Mitzva this Sunday, 29 days before the boy who was born 2 days before him on 29 Adar-1 5757.

A boy who was born on 30 Adar-1 should consult a competent Rabbinic authority how to proceed, as there's a dispute if he becomes Bar Mitzva on Rosh Chodesh Adar or Rosh Chodesh Nissan.
