TL;DR

Major League Baseball operates a rigorous schedule beginning with Spring Training in February and ending with the World Series in late October. The 2025 regular season runs from 27 March to 28 September. Following the regular season, a multi-round postseason tournament determines the champion. Most viewers find the mid-season All-Star Game in July a perfect focal point for the year.

When Do the First Pitches Traditionally Happen?

The MLB season typically begins with Spring Training in mid-February, followed by Opening Day in late March or early April. Early games often include international showcases to expand the global reach of the sport.

Spring Training serves as a warm-up period in Florida and Arizona. Teams play exhibition games to finalise their 26-man rosters. Once the regular season starts, the pace accelerates quickly with games occurring almost daily.
