Avrahom asks:
I was wondering if it is safe to assume that it was beyond a reasonable doubt e.g. she was already showing advanced female development when she was 11, and by 12 day of birth; she could be mistaken for an 18 yo woman that Shmuel would not be choleik on Rav?
A side question which I should have asked in cheder. When we are going strictly by 12 -6 months naarus- bogeres. Is that Lunar years or Solar years?
Avrahom, United States
The Kollel replies:
Dear Avraham,
Rav and Shmuel argue on the Day she changed status, if it happened in the morning. In your case she has been a Bogeres already before today.
Answer2- according to lunar year. There is a proof from the Yerushalmi that the new moon is connected to the physical change.
All the best,
