The 2004–05 NHL lockout resulted in the cancellation of what would have been the 88th season of the National Hockey League (NHL). It was the first time the Stanley Cup was not given out since 1919, and the first time a major professional sports league in North America canceled a complete season because of a labor issue. The lockout lasted 310 days starting September 16 2004, the day after the collective bargaining agreement (CBA) between the NHL and the NHL Players Association (NHLPA) that resolved the 1994–95 lockout expired. The two sides reached an agreement on July 13, 2005, and the lockout ended nine days later on July 22, after both the NHL owners and players accepted the CBA.
