1923 in Judaism

Yehuda Meir Shapiro (or Shapira) (March 3, 1887 – October 27, 1933), was a prominent Polish Hasidic rabbi and rosh yeshiva, also known as the Lubliner Rav. He is noted for his promotion of the Daf Yomi study program in 1923, and establishing the Chachmei Lublin Yeshiva in 1930.

Daf Yomi (Hebrew: דף יומי, Daf Yomi, "page of the day" or "daily folio") is a daily regimen of learning the Oral Torah and its commentaries (also known as the Gemara), in which each of the 2,711 pages of the Babylonian Talmud is covered in sequence. A daf, or blatt in Yiddish, consists of both sides of the page. Under this regimen, the entire Talmud is completed, one day at a time, in a cycle of approximately seven and a half years. As of today, November 28, 2024, the study is of Tractate Bava Batra, page 156.
