What month did Major League Baseball's regular season officially begin in 2026?

Major League Baseball's 2026 regular season officially commenced in March. The highly anticipated season began on March 25 with a standalone night game featuring the San Francisco Giants hosting the New York Yankees. The following day, March 26, marked the traditional Opening Day for the majority of teams across the league, making it the earliest scheduled traditional Opening Day in MLB history.

Historically, Opening Day for professional baseball leagues often fell during the first week of April. However, in recent years, there has been a noticeable shift, with the season occasionally beginning in the last week of March. This earlier start has become more common, with Opening Day consistently landing on the last Thursday of March since 2023. For devoted baseball fans, Opening Day is much more than just the first game; it's a cherished tradition and a widely recognized symbol of spring and renewal, igniting hopes for a championship season ahead.

The extensive MLB regular season typically spans approximately six months, running from late March or early April through late September or early October. Throughout this period, each of the thirty teams plays 162 games. Beyond the regular schedule, the 2026 season also includes special events such as the MLB Mexico City Series, the All-Star Game in Philadelphia, and the return of the MLB at Field of Dreams game, adding extra excitement and unique matchups for fans to enjoy.
