Enter your child's birthday and your local school system's age cutoff to estimate what year they'll start kindergarten (or the equivalent first year of primary school).
In the US, most states and districts require a child to turn 5 years old on or before a specific date to enroll in kindergarten that fall — commonly around September 1, though the exact date varies a lot by state, and sometimes by district within a state. Many other countries use a similar age-based cutoff for starting primary or reception-year school, though the terminology, exact age and cutoff date differ by country — enter your own local cutoff above if the US presets don't apply to you.
In the US, September 1 is the most common cutoff nationally, as a rough estimate. Outside the US, check your national or regional education authority's website, or contact your local school directly, for the exact age and cutoff date that applies where you live.
In many US districts, parents can delay kindergarten entry by a year for a child who's eligible but not quite ready, sometimes called academic redshirting — policies and any required paperwork vary by district. Similar deferred-entry options exist in some other school systems too, so check directly with your local school if this applies to you.
Yes — cutoff dates and entry ages are set by state, regional or national education policy and can be adjusted over time. If your child's start date is more than a year or two away, it's worth double-checking closer to enrollment time.
No — this is just a planning estimate. Actual enrollment requires registering with your local school district or education authority, providing proof of age and residency, and meeting any other local requirements.
