when does baseball season start and end

For Major League Baseball (MLB), the season usually runs from late March or early April through the end of September for the regular season, with playoffs and the World Series stretching into late October (and occasionally very early November).

Quick Scoop: MLB Season Start and End

• The regular season typically:
  • Starts in late March or very early April.

* **Ends** in the final days of September.

• The postseason :
  • Starts right after the regular season, around late September or very early October.

* Ends with the World Series in late October; Game 7, if needed, can push things right to the end of October and occasionally into early November.

For the 2026 MLB season specifically :

• Regular season Opening Night is scheduled for March 25, 2026 , with a Giants–Yankees game, followed by a full Opening Day slate on March 26, 2026.

• The regular season is scheduled to run through September 27, 2026.

• The postseason is set to begin September 29, 2026 , and the World Series is scheduled so that a decisive Game 7 would land on October 31, 2026.

So in simple terms: MLB baseball runs roughly late March to late October each year , with regular-season games ending around late September and playoffs taking over from there.
