Each Major League Baseball (MLB) team plays 162 games during the regular season. The season typically spans about six months, from late March or early April through late September or early October

. The 162-game schedule is structured as follows:

• 52 games within the team's division (13 games against each of the 4 divisional opponents)
• 64 games against other teams in the same league but outside the division (six or seven games against 10 other league teams)
• 46 interleague games against teams from the other league, including matchups with designated rivals

With 30 teams in MLB, this results in a total of 2,430 regular-season games played league-wide each year, excluding postseason games

. The schedule is demanding, with teams often playing nearly every day, organized mostly in series of consecutive games against the same opponent to reduce travel strain

. Occasionally, weather or other unforeseen events can cause cancellations or postponements, sometimes leading to fewer than 162 games played by a team. There can also be extra tie-breaking games if necessary to determine playoff qualification

. In summary, the standard MLB regular season consists of 162 games per team, making it one of the longest and most grueling schedules in professional sports
