This retirement age calculator shows how old you will be—or were—on a planned retirement date. Enter date of birth and retirement day to align benefits planning, pension estimates, and personal timelines.

Full retirement age for Social Security may differ from personal retirement targets—use this for calendar age on a date, not benefit rules alone.

How to use this tool

Enter date of birth and set calculation date to your planned last workday or benefits start date.

Worked example

Example: born April 2, 1965, retiring July 1, 2030 → 65 years, 2 months, 29 days on retirement day.

When to use this

  • Planning a target retirement year.
  • Checking age at pension eligibility dates.
  • Coordinating spouse retirement timelines.

Common examples

  • Born March 15, 1990 → age on July 7, 2026 is 36 years, 3 months, 23 days.
  • School cutoff Sept 1 → compare two children's ages on that date for kindergarten eligibility.
  • Retirement planning → age in years and months on a target retirement date.
  • Birthday countdown → days until next birthday from today's date.
  • Form entry → exact age in years, months, and days for insurance or travel paperwork.

Common mistakes

  • Confusing calendar age with years of service.
  • Using fiscal year instead of actual retirement date.
  • Ignoring that Medicare eligibility is separate from full retirement age.

How it works

Calculates the exact age from a date of birth to a chosen date by counting complete years, then months, then days. Future dates of birth are rejected.

Limitations

Counts calendar years, months, and days between dates. Does not account for time zones or leap-second adjustments.
