How the age is worked out
Subtract the birth year from the current year: 2026 − 2009 = 17. That is the age reached on the birthday in 2026. Before the birthday comes round, the person is one year younger, 16. A birth year on its own can never give one age for the whole year, which is why this page shows both.
2009 was not a leap year, so no one was born on 29 February 2009. By the Pew Research Center's definition, people born in 2009 belong to Generation Z (1997 onward; 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.
