An explanation of Daf Yomi from  myjewishlearning.com

Daf yomi (pronounced dahf YOH-mee) is an international program to read the entire Babylonian Talmud — the main text of rabbinic Judaism — in seven and a half years at the rate of one page a day. Tens of thousands of Jews study daf yomi worldwide, and they are all quite literally on the same page — following a schedule fixed in 1923 in Poland by Rabbi Meir Shapiro, the founder of daf yomi, who envisioned the whole world as a vast Talmudic classroom connected by a global network of conversational threads.
