よくある質問
How is my retirement date calculated?
A retirement age is added to your birth date with month-end clamping, or you can enter a specific retirement date. A specific date takes priority and the tool never infers a legal age.
How many days are left until retirement?
The countdown is the natural-day difference between the calculation date and your planned retirement date. The retirement date itself is not included in work-day estimates.
How are weekends and fixed days off counted?
The tool counts selected fixed weekdays between the day after the calculation date and the day before retirement. Saturday–Sunday pairs are shown separately when applicable.
Are future vacation days exact?
No. Future paid leave, working-day public holidays and the resulting working-day total are estimates based on your annual values and selected retirement-year method.
Is my birth date uploaded or stored?
No. Calculations happen locally in your browser. Dates are not placed in the URL, saved for later or sent to analytics.
