Daf Yomi

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, December 24, 2024,^(refresh) the study is of Tractate Sanhedrin, page 7.

Tens of thousands of Jews worldwide study in the Daf Yomi program,^[1] and over 300,000^[2] participate in the Siyum HaShas, an event celebrating the culmination of the cycle of learning. The Daf Yomi program has been credited with making Talmud study accessible to Jews who are not Torah scholars,^[3][4] contributing to Jewish continuity after the Holocaust,^[3] and having a unifying factor among Jews.^[5][6] Each day of the daily calendar, including Tisha B'Av, is included,^[7] and online audio versions of lectures are available.^[8]

The novel idea of Jews in all parts of the world studying the same daf each day, with the goal of completing the entire Talmud, was first proposed in a World Agudath Israel publication in December 1920 (Kislev 5681) Digleinu, the voice of Zeirei Agudath Israel,^[9] by Rabbi Moshe Menachem Mendel Spivak,^[10][11] and was put forth at the First World Congress of Agudath Israel which took place in Vienna starting from Elul 3, 5683 / August 15, 1923 and which lasted for ten days.^[12] The proposal for the study of Daf Hayomi was made on Elul 7 or 9, 5683 (August 19 or 21, 1923)^[13] by Meir Shapiro, then rabbi of Sanok, Poland, and future rosh yeshiva of Yeshivas Chachmei Lublin and the resolution was adopted on Elul 10, 5683.^[14] In those years, only some of the 63 tractates of the Talmud were being studied regularly, such as Berachot, Shabbat, and Eruvin, which deal with practical laws, while others, such as Zevachim and Temurah, were hardly studied.^[15] Shapiro also viewed the program as a way to unify the Jewish people. As he explained to the Congress delegates:

What a great thing! A Jew travels by boat and takes gemara Berachot under his arm. He travels for 15 days from Eretz Yisrael to America, and each day he learns the daf. When he arrives in America, he enters a beis medrash in New York and finds Jews learning the very same daf that he studied on that day, and he gladly joins them. Another Jew leaves the States and travels to Brazil or Japan, and he first goes to the beis medrash, where he finds everyone learning the same daf that he himself learned that day. Could there be greater unity of hearts than this?^[16][17][18]

Originally, Shapiro saw Daf Yomi as an obligation only for the religious youth of Poland. However, the idea was greeted enthusiastically by the nearly 600 delegates at the Congress, including many Torah leaders from Europe and America, who accepted it as a universal obligation for all Jews.^[15][19]

The first cycle of Daf Yomi commenced on the first day of Rosh Hashanah 5684 (11 September 1923), with tens of thousands of Jews in Europe, America and Israel learning the first daf of the first tractate of the Talmud, Berachot. To show support for the idea, the Gerrer rebbe, Avraham Mordechai Alter, learned the first daf of Berachot in public on that day.^[15][18] On 12 November 1923 Tractate Berachot was completed, with small siyums (celebrations marking the completion of study of a Talmudic tractate) in local communities. At that time, Shapiro published a calendar for the entire cycle of Daf Yomi study.^[15] (For the first seven cycles, there were only 2,702 pages of Talmud on the schedule; later the Daf Yomi Commission of Agudath Israel increased it to 2,711,^[20] changing the edition used for Tractate Shekalim, taken from the Jerusalem Talmud, to one with more pages.) The siyum for the completion of Tractate Pesachim took place after the laying of the cornerstone for Yeshivas Chachmei Lublin. At that time, Shapiro conceived the idea of contributing daily groschen to help raise money for the building. Each day, each person who studied Daf Yomi was asked to set aside a grosh (a Polish penny), and at the end of the tractate, to donate the sum to the yeshiva.^[21]

The Second World Congress of the World Agudath Israel, held in 1929, coincided with the completion of Tractate Zevachim.^[15]

The 1st Siyum HaShas took place on 2 February 1931 (15 Shevat 5691) in several cities in Europe and in Jerusalem, with the main venue being the newly opened Yeshivas Chachmei Lublin in Lublin, Poland. Tens of thousands of Jews attended these events. Shapiro presided over the Siyum in his yeshiva in the presence of many leaders of Polish Jewry.^[22] In the United States, Siyums were held in Baltimore and Philadelphia.^[23]

The completion of the Daf Yomi cycle is celebrated in an event known as the Siyum HaShas ("completion of the Shas").^[24] In America, the main Siyum HaShas is organized by the Agudath Israel of America. Attendance at each successive recent Siyum HaShas has grown. In 1997 the 10th Siyum HaShas was celebrated by some 70,000 participants in the U.S.;^[25] at the 11th Siyum HaShas in 2005, participation had grown to 120,000 in the U.S. and 300,000 around the world.^[2]

The 12th Siyum HaShas in America was held on August 1, 2012, at the MetLife Stadium at the Meadowlands Sports Complex in New Jersey, which has capacity for over 90,000 attendees. All seats were sold out.^[26] Satellite broadcasts were piped to many other locations, including Yeshivas Chachmei Lublin in Poland.^[27] Tens of thousands attended celebrations in Israel.^[28][29][30]

The 13th Siyum HaShas on January 1, 2020, returned to MetLife Stadium, to a capacity crowd.^[31]

Soon after its introduction, Daf Yomi inspired the founding of other Yomi (Daily) study programs for key texts of Judaism. These include Mishnah Yomis (the daily study of Mishnah), Nach Yomi (the daily study of Nevi'im and Ketuvim), and Mussar Yomi (the daily study of Mussar literature).^[52] In 1980 Simcha Bunim Alter introduced Yerushalmi Yomi, a daily schedule for completing the entire Jerusalem Talmud.^[53] Dirshu introduced Mishnah Berurah Yomi, a daily learning plan which completes the entire work by Rabbi Yisrael Meir Kagan in seven years.^[54]

In 2018, Eli Stefansky founded the Mercaz Daf Yomi (MDY) in Ramat Beit Shemesh, from which he broadcasts daily lectures of the daf yomi. As of 2023, the daily lectures received between 16,000^[55] and 18,000 viewers, making its the most popular shiur in the world. He spends an estimated 14 hours per day to prepare for his lectures.^{[56][57][58][59]}
