when was the last time all mlb teams opened on the same day
Opening Day Major League Baseball had most of its teams open the 2011 season on a Thursday (March 31) or Friday (April 1) rather than the traditional Monday, in order to prevent the World Series from extending into November.[23] Similarly, most teams opened the 2012 season on Thursday (April 5) or Friday (April 6). However, subsequent seasons through 2017 returned to Monday openers for most teams. For the 2018 season, all 30 teams were scheduled to open the season on Thursday, March 29 (the earliest domestic start for a regular season in MLB history, and the first time since 1968 that all major league teams were scheduled to start the season on the same day, although two games were subsequently rained out and postponed to Friday, March 30).[24]
Major League Baseball Major League Baseball (MLB) is a professional baseball organization, the oldest of the four major professional sports leagues in the United States and Canada. A total of 30 teams play in the National League (NL) and American League (AL), with 15 teams in each league. The NL and AL were formed as separate legal entities in 1876 and 1901 respectively. After cooperating but remaining legally separate entities beginning in 1903, the leagues merged into a single organization led by the Commissioner of Baseball in 2000.[6][7] The organization also oversees Minor League Baseball, which comprises about 240 teams affiliated with the Major League clubs. With the World Baseball Softball Confederation, MLB manages the international World Baseball Classic tournament.
