Japan School Year Calculator & Table

Enrolment and Graduation Year Table

Japanese résumés list school history by these academic years. The table uses the same assumptions as the calculator above: a school year covers people born 2 April through 1 April of the following year, progressing through 6 years of elementary, 3 of junior high and 3 of high school without repeating a year. The university column assumes a four-year course entered directly after high school. To write these years in Japanese eras, use the era converter and year table.

Born 1985–2010

Someone born on 1 April belongs to the earlier school year. A child born 1 April 2018 starts elementary school in April 2024; one born 2 April 2018 starts in April 2025.

How to Use the Japanese School Year Calculator

Enter a child's birth date to see the elementary school entry year, the current grade for a reference date, and the expected high-school graduation year under Japan's April-to-March school calendar.

This is useful for families moving to Japan, international schools explaining Japanese grade placement, and anyone comparing Japanese grades with school systems that start in August or September.

How the Japanese school year works

Unlike countries that start school in September, the Japanese school year runs from April to March. A child joins the cohort that reaches the entry age during that year, with April 2 as the cut-off: children born on or after April 2 enter one year later than those born up to April 1, so an April 1 birthday is the youngest in the grade. This calculator applies that Japanese rule, which is why entry lands in April and graduation in March.

Japan’s Ministry of Education explains the legal age calculation and the cohort boundary in its official guidance on April 1 birthdays: a grade normally consists of children born from April 2 through April 1 of the following year (last checked July 14, 2026).

Examples

• Born 2018-04-01 → enters April 2024; grade 2 in FY2025
• Born 2018-04-02 → enters April 2025 (one year later)

What the Result Means

The grade shown is based on the Japanese school year that contains the reference date. For example, a date in May 2026 belongs to school year 2026, while a date in February 2027 still belongs to that same school year because it ends in March.

Assumptions and limits

The estimate assumes continuous progression through six elementary, three junior-high, and three high-school years. It does not model grade repetition, accelerated progression, deferred enrollment, transfers, international schools, or a school with a different academic calendar. Use school records for applications and other official dates.
