How old is someone born in 2000?
Subtract 2000 from 2026 to get 26. If the person's birthday has not happened yet this year, subtract one, making the age 25. 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 2000 turns 26, but before that birthday they remain 25.
About generation labels
Generation Z is a commonly used label for people born in this period. Generation boundaries vary by source and are descriptive, not scientific or legal categories.
