Siyum HaShas is a celebration of the completion of the Daf Yomi program, a roughly seven-and-a-half-year cycle of learning the Oral Torah and its commentaries, in which each of the 2,711 pages of the Babylonian Talmud are covered in sequence – one page per day. The first Daf Yomi cycle began on the first day of Rosh Hashanah 5684 ; the thirteenth cycle concluded on 4 January 2020 and the fourteenth cycle began the following day, to be concluded on 7 June 2027. The Siyum HaShas marks both the end of the previous cycle and the beginning of the next, and is characterized by celebratory speeches, as well as singing and dancing. The next day, the new cycle begins again.

Daf Yomi is a daily regimen of learning the Oral Torah and its commentaries, 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.
