Division Series (LDS): Best-of-five series following Wild Card round
Championship Series (LCS): Best-of-seven series for AL and NL titles
World Series: Best-of-seven series between AL and NL champions

Factors That Can Affect the End Date of the Season

While the official schedule sets firm dates, several variables can influence when baseball truly ends each year.

Potential Delays or Extensions

Weather-related postponements: Rain delays during the regular season or playoffs may push games back
Tiebreaker games: If teams finish with identical records affecting playoff qualification, an extra game may be needed
World Series length: A sweep (4-0) ends the season earlier; a full seven-game series extends it by up to three days
Broadcast scheduling: Networks like Fox and ESPN influence start times and potential day-to-day adjustments
