Little League Age Calculator

League age, not birthday age, decides which Little League division a player registers in. Enter the date of birth, pick baseball or softball and give the season year, and this returns the league age, the determination date it used, and the divisions that age fits. Baseball uses the player's actual age on 31 August of the season year, while softball uses the age on 31 December of the year before, which is why the same child can have two different league ages. Your local league still confirms eligibility, because a local board may narrow a division to a shorter age range.
