For general information only — not medical advice. Results are estimates; talk to a doctor or qualified health professional about your own health.
How to use
- 1Enter the child's birthdate and the school year you're asking about.
- 2Set your state or country's cutoff date (September 1 is common in the US).
How it's calculated
A child starts kindergarten in the school year that begins in the calendar year they turn 5 on or before the cutoff date. Grade = school year start − that year (K = 0).
Frequently asked questions
What's the kindergarten cutoff in my state?
Many US states use September 1; others use dates from August to January. Check your state education department.
How does this work in the UK?
England's school year runs 1 September to 31 August; children start Reception the September after they turn 4. Set the cutoff to September 1 and read 'K' as Reception.
Can parents choose to delay kindergarten?
In most US states, yes ('redshirting'). This shows the usual entry year only.
