Dates of the Chasam Sofer , Tzrichim Limud

Mori V’rabi Hagaon R. Y.M. Hirschman shlita, told me the Chasam Sofer

writes  Befeirush in the Hagahos on O. Ch. 551, also in the Drashos 2: p331.

“After 9^th Av a new month starts called Menachem.”

I leafed through the seven volumes of Shu”t  Ch. S. (1246 Teshuvos)

and found, there are aproximately 150 Teshuvous written by the Chasam Sofer

in the month of Av. All of them follow the rule of the TchebinerRav zt”l,

The ones dated Before 9^th Av are dated as Av. The ones after 9^th Av are dated as

Menachem.

However there are two days, the 13^th and 15^th of Av  where the Ch. S. dates them

Av, even though they are after 9^th Av.

It is possible the 15^th of Av being it is mentioned in the Mishna (end m. Ta’anis)

as Chamisha Asar B’av, he didn’t  want to change the Loshon of the Mishna*.

On the 13^th of Av I have no explanation.

15^th of Av                      13^th of Av

O.Ch. 60                         O.Ch. 115
