Calculate an exact age

How old is someone born in 1966?

Subtract 1966 from 2026 to get 60. If the person's birthday has not happened yet this year, subtract one, making the age 59. A full birth date is needed for an exact result in years, months, and days.

Why two ages are shown

A birth year alone does not include the month and day. During 2026, everyone born in 1966 turns 60, but before that birthday they remain 59.

About generation labels

Generation X is a commonly used label for people born in this period. Generation boundaries vary by source and are descriptive, not scientific or legal categories.
