What Generation Am I Calculator

Find your generation by birth year and see your age in any reference year.

Use this generation calculator to quickly see which generation a birth year belongs to and how old that person will be in a chosen reference year. It is useful for audience research, school projects, cultural comparisons, family conversations and content that talks about generational habits or trends.

Enter the birth year and the year you want to compare against. The tool returns the generational label, the range used for that cohort and the birth decade, which makes it easier to place someone in groups such as Baby Boomers, Generation X, Millennials, Generation Z, Alpha or Beta.

Generation boundaries are not identical in every study, so this calculator follows a widely used general model. That makes the result practical for quick answers while still giving enough context to understand the cohort behind the label.

Leave the reference year on the current year if you want the present age.
