Enter your child's date of birth — get their exact age as of your state's admission cutoff date, down to the day.
Verify before you decide. RTE and school admission age-cutoff rules are set independently by each state (and sometimes vary by school), and can change between admission cycles. The examples above are a starting point, not a guarantee — always confirm the exact cutoff date and minimum age against your own state's current official notification or your target school directly.
The genuinely hard part of an age-cutoff rule isn't the rule itself — it's correctly computing a child's exact age (years, months, and days) as of an arbitrary future date, which is easy to get wrong doing it by hand. This tool automates that date math and shows the full result, while leaving the actual age criteria fully editable, since those numbers are set independently by each state and change between admission cycles.
A few real examples we found (enter your own state's actual rule if it differs):
Since implementation is decentralized, treat every preset above as a starting example, not your state's confirmed rule.
