How the age is worked out

Subtract the birth year from the current year: 2026 − 1984 = 42. That is the age reached on the birthday in 2026. Before the birthday comes round, the person is one year younger, 41. A birth year on its own can never give one age for the whole year, which is why this page shows both.

1984 was a leap year, so it had a 29 February. Someone born that day turns a year older on 28 February in common years, the convention this site uses throughout. By the Pew Research Center's definition, people born in 1984 belong to Millennials (1981–1996; source: Pew Research Center, 17 January 2019). Other sources draw some boundaries differently; see what generation am I.
