USSSA Age Calculator
USSSA baseball and fastpitch use different dates. In baseball, a player who turns N+1 before May 1 of the season is too old for NU, unless a grade exception applies. In fastpitch (from the 2026 season), the player's age on August 31 before the season sets the division.
Before you start
Method : Age on the USSSA date for the chosen sport and season; baseball grade exception checked against the August 1 limit.
Checked : Rules read from the 2026 USSSA baseball by-laws and fastpitch 2026 age chart on 2026-10-05; boundary tests for the day before, on and after each date.
Review : not reviewed by USSSA; not affiliated with USSSA.

How to Use This Calculator
- Choose baseball or fastpitch and the season (a USSSA season is named for the year it ends).
- Enter the birth date.
- Press Calculate.
Methodology & assumptions
Step 1 — rules for your selection: sport and season pick the stored rule (checked 2026-10-05; verified for the 2026 season). A baseball season starts the second Tuesday of August and ends the next summer, so the 2026 season's only May 1 is May 1, 2026.
Step 2 — date arithmetic. Baseball: age on April 30 = home division (4U–18U). Grade exception: one division younger if in the listed grade and still under N+2 on July 31. Fastpitch: age on August 31 of the previous year.
Worked examples
Baseball 2026: turns 13 on April 30, 2026 → 13U; on May 1 or May 2, 2026 → 12U.
Grade exception, 2026: born January 15, 2013 (13 on April 30) → 13U, or 12U if in 6th grade. Born July 31, 2012 → turns 14 before August 1, so no exception.
Fastpitch 2026: born August 31, 2013 → 12 on August 31, 2025 → 12U; born September 1, 2013 → 11U.
