when does baseball season end

The Major League Baseball (MLB) regular season for 2025 ends on September 28. This marks the conclusion of the 162-game regular season for all teams, after which the postseason (playoffs) begins shortly thereafter. Minor league baseball seasons end earlier in September, with Triple-A ending around September 21, Double-A around September 14, and Single-A by September 7. The college baseball season ends earlier in June with the College World Series. The MLB postseason then follows in October, extending the baseball calendar beyond the regular season end date.
