Rabbi Nosson Dovid Rabinowich will be delivering his last Pirkei Avos shiur of the season on September 6, 2015/21 Elul 5775. There are eighteen or nineteen Shabboses between Shavuos and Rosh Hashana, which have Pirkei Avos shiurim. I say “eighteen” because according to Rav Moshe Isserles (see about him in our first blogs re: Lag B’Omer), Orach Chaim 553:2 we do not study Avos if Tisha B’Av ever falls on Shabbos, as it did this year. We therefore, lost a Shabbos and the chapter for Shoftim was Chapter 6. Other calendars offer chapter one as the study chapter for Parshas Shoftim.
