When Does March Madness Start? Key Dates You Need to Know

March Madness 2026 is set to ignite college basketball fans’ excitement starting mid-March. Selection Sunday kicks off the spectacle on Sunday, March 15, when the 68-team brackets are revealed. That announcement launches the tournament’s fast-paced, high-stakes action—including the “First Four” play-in games beginning Tuesday, March 17, and the tournament building toward its dramatic championship on Monday, April 6. This article lays out the essential dates and venues you need to follow the madness.

Why These Dates Matter

Selection Sunday is when college basketball fans learn which teams have made the cut for the NCAA Tournament—both men’s and women’s. With the men’s bracket revealed at 6 p.m. ET on CBS and the women’s bracket following at 8 p.m. ET on ESPN, it’s the moment the bracket frenzy truly begins.

From there, the First Four games determine the final spots in the full bracket, setting up matchups in the main draw starting just days later. For athletes, coaches, broadcasters, and fans, knowing the timeline is key for planning travel, viewing parties, or filling out brackets.
