If you were born in 2001
If you were born in 2001, you turn 25 during 2026. You are 24 until your birthday in 2026, then 25 afterwards. Enter your date of birth below for your exact age.
The age you reach during a calendar year is that year minus your birth year: 2026 − 2001 = 25. You are one year younger until your birthday falls, then you are 25 for the rest of 2026.
Someone born in 2001 belongs to Generation Z, and at 25 is of working age; UK pension auto-enrolment applies from 22 up to State Pension age.

How it works.
Rule: age = current year − birth year, minus 1 if this year's birthday has not happened yet.
- Subtract the birth year: 2026 − 2001 = 25.
- If today is before the birthday in 2026, subtract 1 → 24.
- The calculator above does this exactly from your full date of birth.
