What is a School Age Calculator?

A school age calculator estimates whether a child meets a selected school entry age by a cutoff date. It is useful for kindergarten eligibility, preschool planning, grade 1 checks, and school enrollment questions when rules depend on date of birth. Because cutoff dates vary by country, state, district, and school, this calculator lets you enter the school year start date, cutoff date, and minimum age instead of assuming one rule. The result shows age on the cutoff date, age when school starts, whether the child meets the selected age rule, and the next likely eligible school year if the cutoff is missed.

Example school age result

If a child was born on October 5, 2021, the school year starts on August 15, 2026, and the kindergarten cutoff is September 1, 2026, the result explains the cutoff clearly.
