What Is League Age in Little League?

League age is not the same as a child’s actual birthday age. Little League International uses a fixed cutoff date every year to determine which division a player belongs to. That date – not the season start – decides everything.

For the 2026 season, the official age determination date for baseball is August 31, 2026. A player’s league age is how old they are on that date. A child born on September 1, 2014 is still considered league age 11 for the entire 2026 season — because they have not yet turned 12 by August 31.

Before 2018, the baseball cutoff was April 30. Little League changed it to August 31 to better align with the tournament dates in August and give borderline-age players a fairer eligibility window. The change meant fewer players were caught in grey areas near the tournament date.

Not always. League age is a player’s age on the official cutoff date – August 31 for baseball. A child who turns 12 on September 15 is still considered league age 11 for the entire 2026 season. They will be league age 12 for the 2027 season.
