Both teams are members of the American League and National League structure that has governed the sport since the early 20th century.

Each season consists of 162 regular-season games followed by a postseason tournament that includes wild card rounds, division series, championship series, and the World Series.

The concept of a "season" in Major League Baseball is standardized across all 30 teams, with each franchise playing a 162-game regular season typically spanning late March or early April through late September or early October. Spring training precedes the regular season, usually starting in mid-February, and the postseason extends into late October or November when teams reach the World Series. The Chicago Cubs joined the National League in 1876, giving them one of the longest continuous histories in professional North American sports. The Chicago White Sox were founded in 1900 and entered the American League in 1901. Both teams have experienced periods of championship success and rebuilding, but their total season counts continue to grow by one each year. The number of seasons is a key metric for comparing franchise longevity and historical performance across Major League Baseball.
Chi Season Structure and League Organization
Major League Baseball divides its 30 teams into two leagues, the American League and the National League, each containing three divisions: East, Central, and West. The Chicago Cubs play in the National League Central alongside the St. Louis Cardinals, Milwaukee Brewers, Pittsburgh Pirates, Cincinnati Reds, and Milwaukee Brewers. The Chicago White Sox play in the American League Central with the Cleveland Guardians, Detroit Tigers, Kansas City Royals, Minnesota Twins, and Baltimore Orioles. Each team plays 13 games against each division opponent, totaling 52 divisional games, and the remaining 110 games are split between interleague play and series against teams from the other league's divisions. The season structure has remained largely consistent since the early 2000s, with the addition of a 163rd tiebreaker game when necessary to determine division or wild card standings.
The postseason format includes three division winners and three wild card teams per league, seeded by win-loss record. The wild card round features best-of-three series, followed by best-of-five division series and best-of-seven championship series. The World Series, a best-of-seven matchup between the American League and National League champions, concludes the season. The Chicago Cubs won the World Series in 2016, ending a 108-year championship drought, while the White Sox last won the Fall Classic in 2005. The total number of seasons played by each franchise includes all regular-season and postseason campaigns, with the season count increasing by one annually.
