How the age is worked out

Subtract the birth year from the current year: 2026 − 1986 = 40. That is the age reached on the birthday in 2026. Before the birthday comes round, the person is one year younger, 39. A birth year on its own can never give one age for the whole year, which is why this page shows both.

1986 was not a leap year, so no one was born on 29 February 1986. By the Pew Research Center's definition, people born in 1986 belong to Millennials (1981–1996; source: Pew Research Center, 17 January 2019). Other sources draw some boundaries differently; see what generation am I.

The full method, including month ends and leap days, is on the calculation methodology page. To go from an age back to a year, use the birth year calculator.
