The age you reach during a calendar year is that year minus your birth year: 2026 − 1981 = 45. You are one year younger until your birthday falls, then you are 45 for the rest of 2026.
Someone born in 1981 belongs to the Millennial generation (Generation Y), and at 45 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 − 1981 = 45.
- If today is before the birthday in 2026, subtract 1 → 44.
- The calculator above does this exactly from your full date of birth.
