Graduation Year Calculator

Born in 2010? That is the Class of 2028 with a September 1 cutoff, or 2029 if the birthday falls later

Most U.S. states enroll a child in kindergarten when they are 5 by a cutoff date, and the Class of year is 13 school years after kindergarten begins. With the most common cutoff, September 1, a child born between January 1 and September 1, 2010 starts kindergarten in fall 2015, starts 1st grade in fall 2016 and graduates from high school in spring 2028, so they are in the Class of 2028. A child born between September 2 and December 31, 2010 waits a year: kindergarten in fall 2016 and the Class of 2029.

The calculator above does this for any birth year, and it also works backward. Enter a class year, a grade now or an age and it returns the birth dates that fit, with the school year shown as a staircase from pre-K to college. Because cutoffs differ by state, pick the state first. If you only need someone's age on a date, the age calculator is the simpler tool.

When you need to work out a graduation year

• Reunions and class years: a reunion committee asks for the Class of year, but you only remember when you were born, or when you left a school after moving. Working back from a birthday to the Class of year settles which class you belong to.
• Applications and résumés: college and job forms ask for a high school graduation date. When the paperwork is gone, the birth year and state give the year, and your diploma or transcript gives the exact date.
• Planning for a child: a birthday close to the cutoff decides whether a child is among the oldest or the youngest in the class. Knowing the Class of year early helps with childcare, tuition savings and college timelines. To compare ages inside a family, try the parent-child age difference calculator.
• Moving between states: the same birthday can mean kindergarten in one state and another year of preschool in the next. The state picker shows the effect on the Class of year right away.

How the graduation year is calculated

Kindergarten comes first, then grades 1 through 12, so a student who follows the usual path spends 13 school years in K–12. A school year starts in late summer or fall and ends in the spring or early summer, so graduation always falls in the calendar year after the senior year begins. The calculator counts a new school year from July 1, which is why it still shows the 2025–26 grade in June but switches to 2026–27 in July.

A student born on March 15, 2010 starts kindergarten in 2015 and graduates in 2028, then finishes a four-year degree in 2032 if there is no break. The calculator adds elementary school as grades 1–5, middle school as 6–8 and high school as 9–12. Some districts use K–8 or 7–12 buildings instead, but the grade count and the Class of year do not change.

Kindergarten cutoff dates by state

The Education Commission of the States compiled each state's entrance rule from statutes and regulations for its 2026 comparison. September 1 is the most common cutoff, used by 22 of 51 jurisdictions, but the dates run from July 31 to December 31, and a few states leave the decision to districts.

• On or before September 1: Alabama, Alaska, California, Connecticut, Florida, Georgia, Idaho, Illinois, Maryland, Michigan, Minnesota, Mississippi, Oklahoma, Oregon, Rhode Island, South Carolina, South Dakota, Texas and Wisconsin.
• Before September 1, so a September 1 birthday waits: Arizona, New Mexico and West Virginia.
• Early August or July: August 1 in Arkansas, Indiana, Nevada and Wyoming; before August 1 in Kentucky, Missouri and North Dakota; July 31 in Hawaii and Nebraska; August 15 in Tennessee.
• Late August: August 31 in Delaware, Kansas, North Carolina and Washington.
• Later than September 1: Utah September 2, Montana September 10, Iowa September 15, Louisiana, Virginia and D.C. September 30, Colorado and New Jersey October 1, Maine October 15, and Vermont before January 1.
• Local or unspecified: Massachusetts, New York and Pennsylvania let districts set the age, New Hampshire has no statewide rule and Ohio uses the first day of school. The calculator assumes September 1 for these, so check with the district.

One birthday, different Class of years

The cutoff matters most for children born in July through October. Take three birthdays in 2010 and four states with different dates. The same child can be in the Class of 2028 in one state and 2029 in the next, and the calculator shows it as soon as you change the state.

Within a state, parents can sometimes request early entrance or hold a child back a year, and districts decide how. The Class of year then moves by one year, so add or subtract one from the result.

Class of year by birth year

This table assumes a September 1 cutoff and a student who moves up one grade every year. Pick another state in the calculator for a different date.

Grade by birth date in the 2026–27 school year

With a September 1 cutoff, each grade holds children born from September 2 of one year through September 1 of the next. In Arizona, New Mexico and West Virginia every range starts and ends one day earlier, and other states shift it to their own date. These rows are valid from July 1, 2026 to June 30, 2027.

Working back from a class year, a grade or an age

Subtract 13 from the Class of year to get the kindergarten year, then subtract 5 more for the birth year. For the Class of 2030, kindergarten began in fall 2017, so with a September 1 cutoff the students were born between September 2, 2011 and September 1, 2012. Under the same rule a 10th grader in 2026–27 is in the Class of 2029, because 10th, 11th and 12th grade are still ahead.

Starting from an age needs one extra step, because the birth year depends on whether this year's birthday has passed. On October 18, 2026, a 16-year-old was born between October 19, 2009 and October 18, 2010. Most of that range is the Class of 2028, but the 47 days from September 2 to October 18, 2010 fall after a September 1 cutoff and lead to the Class of 2029. Add the birth month in the calculator to settle which one applies.

College years and what comes after

The National Center for Education Statistics describes an associate degree as at least 2 years of postsecondary coursework and a bachelor's degree as typically 4 years. The calculator uses those lengths, plus 2 years for a master's degree as a common length, though programs differ. For a student in the Class of 2028, an associate degree ends in 2030, a bachelor's degree in 2032 and a master's degree in 2034, if each starts right after the previous one. A gap year before college or time off during it moves every later year back by that amount, and the gap controls under the school list handle it.

Graduation dates on résumés and applications

• Still in high school in the Class of 2028: write "Expected June 2028", or the month your school holds graduation.
• Already graduated: the year alone is enough, for example "High School Diploma, 2024".
• GED or another equivalency: list the year you earned the credential instead of a Class of year.
• College "Class of" is the spring you finish a four-year degree, so a high school Class of 2028 student who goes straight to college is usually in the college Class of 2032.
• If a form needs an exact day, take it from the diploma or transcript rather than from a calculation.

When the result can be different

• Waiting a year to start kindergarten ("redshirting") or repeating a grade adds a year to every later date.
• Early entrance that a district allows, or skipping a grade, takes a year off.
• Transitional kindergarten and pre-K can come before kindergarten without changing the Class of year, which is why the calculator shows pre-K as an extra column.
• After a move, the new school may place a student by age or by records, so the grade can differ from the table.
• Cutoffs change by law. The calculator uses the dates in the 2026 ECS comparison, so check your district for an enrollment decision.

As of The cutoffs were checked against the ECS 2026 report on October 18, 2026, and every year in this article was calculated on the same day. The 2026–27 school year runs from July 1, 2026 to June 30, 2027 in the calculator.
