Enter a player’s birth month and year to see the league age and division for the 2027 season in Little League, PONY and Babe Ruth League’s Cal Ripken program, plus the field distances and bat rule for each division. Every figure comes from the governing body’s own page, linked below. Little League’s own calculator only covers Little League; this puts the three side by side.
League age and field finder
This finder needs JavaScript. The tables below give the same information without it.
Always confirm with your local league. Little League, PONY and Babe Ruth League all let local leagues choose narrower age ranges, shorter regular-season distances and their own bat lists. Treat this page as the national rule, not your league’s final answer.
How league age works in each program
- Little League (baseball): league age is a player’s actual age on August 31 of the season year (Little League’s age determination page). Its 2027 age chart shows the same thing by birth month.
- PONY: the cutoff is April 30. PONY’s board moved it from August 31 in 2022 (PONY league age key), so older articles that say August 31 for PONY are out of date.
- Babe Ruth League (Cal Ripken): “May 1 in any year shall be the deciding date” (Babe Ruth League age chart). When we checked, only the 2026 chart was posted, so the 2027 results here apply the same May 1 rule to the 2027 season. We cross-checked the rule against the 2026 windows; confirm the 2027 chart once it appears.
League age by birth date, 2027 season
We checked this formula against all 156 cells of Little League’s 2027 chart and all 252 cells of PONY’s 2027 key. Every cell matched.
