Typical ages during the 2026–27 school year (United States). A student's age changes on their birthday, so each grade spans two ages; held-back, skipped, and gap years shift the result.

Birth Year by Age (2026)

Someone who is a given age this year was born in one of two years, depending on whether their birthday has already passed.

As of October 26, 2026, someone who is 18 was born between October 27, 2007 and October 26, 2008.

How to Estimate Age From a Graduation Year

Start with the typical graduation age, then allow for birthdays, cutoff rules, and different school paths.

High School Graduation Year to Age

Most US students graduate high school at 17 or 18. With a September 1 kindergarten cutoff, a class is born from September, 19 years before graduation, through August, 18 years before. For example, the Class of 2012 was born between September 1993 and August 1994. Subtract those birth years from the current year to get the age range.

College Graduation Year to Age

A typical four-year college graduate is 21 or 22, so a college class was usually born 22 to 23 years before graduation. Three-year degrees, common in England, Australia, and India, finish about a year earlier. Gap years, transfers, and part-time study can shift the estimate.

School Start Years From a Graduation Year

Count back from the graduation year. In the US, 9th grade starts 4 years earlier, 6th grade 7 years earlier, and kindergarten 13 years earlier. The timeline under the calculator lists these years for any class.

School Systems Outside the US

Canada groups students by calendar birth year (a December 31 cutoff in most provinces). England and Wales use September–August like the US, with Reception before Year 1. Australian classes run roughly July–June but vary by state. The Philippines added Grades 11–12 in 2016, and India usually groups students April–March.

School Age and Graduation Year From Date of Birth

When a birthday is known, use the Birthday → School Years tab for a fuller US school timeline. September 1 is a common cutoff example, but rules vary by state and district.
