Find a child's school start year and complete grade timeline by country and region, or calculate exact age for a custom cutoff or testing date.

Choose a location for an automatic planning rule, see the full school timeline, or use an exact custom cutoff.
Guide
School entry is organized differently across countries and regions. A five-year-old may enter Kindergarten, Reception, Foundation, Prep, Primary 1, or another locally named stage. Location mode selects a planning rule and the correct terminology before calculating the first entry year and later school stages.
The calculator finds the first school year in which the child reaches the required entry age by the regional cutoff. A birthday one day after the cutoff normally moves the planning estimate to the following intake. The result displays the exact age on the cutoff so close boundary cases remain visible.
After estimating the first entry year, the tool maps every later stage using the terminology of the selected education system. The table shows the school year and age reached during each stage, including the final listed year. It is a planning sequence, not a guarantee that a child will never repeat, accelerate, transfer, or defer.
District-set policies, private schools, early-entry programs, and assessments often need an exact local date. Custom cutoff mode applies the school's stated minimum age, while exact-age mode produces reproducible years, months, days, total months, and total days for testing or records. These modes avoid forcing a regional preset onto a context it does not cover.
Use location mode for early planning when its evidence label fits the decision, then confirm enrollment with the responsible authority. Canada and Australia link every supported jurisdiction to a first-party government source. The United States baseline now uses the June 2023 Education Commission of the States statute comparison, with current first-party sources for rules specifically reverified in 2026; district-controlled US states and Saskatchewan require a user-entered current cutoff instead of silently applying a placeholder date.

Step 2
School entry is organized differently across countries and regions. A five-year-old may enter Kindergarten, Reception, Foundation, Prep, Primary 1, or another locally named stage. Location mode selects a planning rule and the correct terminology before calculating the first entry year and later school stages.
Step 3
Regional rule: The selected location supplies entry age, cutoff month and day, school-year pattern, local terminology, and a directly displayed evidence level. First entry intake: The first intake is the earliest supported intake in which completed age on the cutoff reaches the stated requirement. South Australia: The calculator models both Term 1 and Term 3 Reception entry and carries the six-term mid-year Reception sequence into the later timeline. Timeline: One stage is added per school year except where a published intake explicitly changes the first-stage duration; repetition, acceleration, transfer, and deferral are not assumed. Override: A local cutoff replaces the preset month and day while preserving the selected education-system timeline.
Step 4
Estimated Kindergarten start: 2027–2028. The birthday falls one day after the September 1 planning cutoff, so the estimated intake moves to the following year.
Location mode provides a reproducible planning estimate from a jurisdiction-linked rule. Local authorities and schools remain responsible for enrollment and placement.
| Assumption | How this page handles it |
|---|---|
| Regional rule | The selected location supplies entry age, cutoff month and day, school-year pattern, local terminology, and a directly displayed evidence level. |
| First entry intake | The first intake is the earliest supported intake in which completed age on the cutoff reaches the stated requirement. |
| South Australia | The calculator models both Term 1 and Term 3 Reception entry and carries the six-term mid-year Reception sequence into the later timeline. |
| Timeline | One stage is added per school year except where a published intake explicitly changes the first-stage duration; repetition, acceleration, transfer, and deferral are not assumed. |
| Override | A local cutoff replaces the preset month and day while preserving the selected education-system timeline. |
| Input | Output | Why it matters |
|---|---|---|
| California; born 2021-09-02 | Estimated Kindergarten start: 2027–2028 | The birthday falls one day after the September 1 planning cutoff, so the estimated intake moves to the following year. |
| England; born 2022-06-15 | Estimated Reception start: 2026–2027 | The child turns four before the August 31 cohort cutoff. |
| Born 2018-02-28; test date 2026-03-01 | 8 years, 0 months, 1 day | Exact-age mode respects real month lengths and leap years. |
| Born one day after the regional cutoff | Estimated first entry moves to the following supported intake | The exact cutoff age and intake name remain visible for verification. |
| South Australia; turns five between May 1 and October 31 | Term 3 mid-year Reception intake | The timeline shows six terms of Reception before Year 1. |
Edge cases
A planning preset cannot replace the current district calendar. Use the local cutoff override when the authority publishes a different date.
Readiness assessments, summer-born deferral, Transitional Kindergarten, mid-year intake, and waivers follow separate rules that require local review.
The timeline assumes one stage per year after first entry. A school record takes precedence when the child has already enrolled.
Exact-age mode applies a consistent calendar convention, but the authority controls how a February 29 birthday is treated for eligibility.
Use location mode for early school-entry planning and a full grade timeline; use custom or exact-age mode when a school, district, test, or program supplies its own official date.
Do not treat the estimate as an enrollment or placement decision. Confirm the current cutoff, exceptions, deferral route, residency rules, and existing school record with the responsible authority.
Choose the country and region and enter the birth date. The tool finds the first intake in which the child reaches the preset entry age by the cutoff, then shows the full timeline.
No. It assumes continuous yearly progression from the estimated first entry. Existing records, transfers, deferrals, acceleration, and school decisions can change placement.
Enable the local cutoff override or use custom cutoff mode, then confirm the result with the school.
Yes. Exact-age mode calculates chronological age on a testing, evaluation, or record date.
Some jurisdictions delegate the operational cutoff or exceptions to districts. The calculator withholds an automatic answer until you enter the current local date.
Children turning five from May 1 through October 31 can start Reception in Term 3 and complete six terms of Reception; the displayed timeline accounts for that extra half-year.
No. Only the school or governing authority can apply waivers, readiness rules, deferrals, or early-entry pathways.
