Sports & Fitness Age Tools

Two different questions live here. League tools answer "which division can my child play in this season?" using each organisation's own cutoff date. Training tools answer "how hard should I work, and how fit am I for my age?" using published exercise-science formulas.

League rules change by season and program; each page shows the season it was checked for and warns when a rule is unverified. The final word on eligibility belongs to your league. Training estimates vary by person and are not a medical exercise test.
