Chinese age calculatorSchool Timeline for Children Born in 2020
Most US states use a kindergarten cutoff close to September 1, which splits the 2020 birth year in two. Children born before the cutoff usually started school in the fall of 2025, and those born after it in 2026. A state with a later cutoff can move a fall birthday into the earlier group.
The same split will place most children born in 2020 in the high school class of 2038 or 2039. In the 2026 to 2027 school year, a child born in early 2020 is typically in grade 1, while one born in late 2020 is in kindergarten. The age by grade chart shows the full pattern for every grade.
