What You'll Learn

The tournament lasts about three weeks
The NCAA Division I men's basketball tournament, branded as March Madness, is a single-elimination tournament played in the United States to determine the men's college basketball national champion. The tournament lasts about three weeks, starting with the First Four and ending with the title game.
The tournament usually begins in mid-March and concludes in early April. The First Four games are played on Tuesday and Wednesday, followed by the First and Second Rounds, which take place from Thursday to Sunday of the first week. The second- and third-round games are played at eight geographically dispersed sites, and the 16 teams that advance to the second week are referred to as the "'Sweet Sixteen."
During the second week, the remaining teams proceed to four regional sites and are further narrowed down to the "'Elite Eight" and "Final Four." The Final Four advances to another location for the national semifinals and finals in the third week of the competition. The tournament consists of 68 teams, with 32 teams automatically qualifying by winning their conference tournaments, and 36 teams receiving at-large bids based on factors such as strength of schedule and record.
The length of the tournament allows for a substantial field of teams, including both large schools from prominent conferences and smaller automatic qualifiers. This format often results in upsets, with underdog teams, known as "Cinderellas," advancing further than expected. The excitement and unpredictability of March Madness have made it one of the most significant annual sporting events in the United States, with millions of people filling out brackets and following the action.
Each game in the tournament usually lasts around two hours, but this can vary depending on factors such as timeouts, fouls, and overtime. The tournament has become an integral part of American popular culture, with extensive media coverage and bracket contests that award prizes for correctly predicting game outcomes.

The Elite Eight
During the first 12 years of the tournament (1939–1950), only eight teams competed, meaning every team that qualified was automatically an Elite Eight team. In 1951, the tournament expanded to 16 teams, and it has since grown to include 68 teams.
In 2024, the Elite Eight field in the men's NCAA Tournament included the top eight overall seeds, with No. 1 seeds such as UConn, Purdue, and Tennessee vying for a spot in the Final Four.
