Assumptions

Date-only calculations use the proleptic Gregorian calendar and ignore clock time. Elapsed-time calculations and selected-zone conversions state their time basis separately.

Limitations

  • Employer, service, rank, pension, and national rules vary.
  • This estimate is not an official eligibility decision.

Frequently asked questions

What date basis does the Retirement Date Calculator use?

The result uses calendar dates unless the page explicitly describes elapsed time or a selected time zone.

Can daylight-saving time change calendar-day totals?

No. Date-only calculations use normalized UTC day numbers. Elapsed timestamp and time-zone calculations are explicitly handled separately.

Are entered dates stored?

No. Calculations run in your browser and the entered dates are not saved or sent anywhere.
