FAQ
How is age calculated exactly? +
Years are counted whole; the remainder is counted in months, then days. We use calendar months — so 'one month' is anywhere from 28–31 days depending on the calendar.
Why does the 'total days' number look weird? +
Total days is an exact count from your birth date to today, including leap days. It will not match years × 365.
Can I check someone else's age on a specific date? +
Yes — change the 'As of' field to any date. Useful for retirement planning, eligibility checks, or just curiosity.
