Little League Age Calculator
Little League assigns divisions by “league age”, not the player's current age. For baseball it's the player's age on August 31 of the season year; for softball it's the age on December 31 of the year before.

Worked example
Example: baseball player born May 20, 2015, 2027 season
- Age on August 31, 2027
- May 20, 2015 → August 31, 2027 = 12 years
League age 12 — eligible for the Majors division.
Formula
Baseball league age = age on Aug 31 of season year
Softball league age = age on Dec 31 of prior year
These are Little League International rules; other youth organizations (Babe Ruth, PONY, USSSA) use different dates.
Frequently asked questions

Typically Majors (ages 9–12), or Intermediate 50/70 (ages 11–13).
