How this count works
Calendar age counts completed years, then completed months, then the remaining days. Total days lived is the separate whole-day difference between your birth date and the date you choose. For an age at death, enter the date of death as the age-on date. To work backwards from an age to a range of birth dates, choose Birth date from an age.
A February 29 birthday uses February 28 in a non-leap year. A month without the birthday’s day uses its last day. Legal birthday rules can differ.
A worked example
Someone born on February 29, 2000 is 26 years, 6 months and 22 days old on September 19, 2026. That is 9,699 calendar days.
