Perguntas frequentes
How is the age calculated so precisely?
The tool counts full elapsed years, then full elapsed months within the current year, then remaining days, accounting for different month lengths and leap years, rather than just dividing total days by 365. That's why the months/days breakdown matches how people naturally describe their age.
Can I calculate age as of a date other than today?
Yes, the "As of" field defaults to today but you can set it to any date, useful for calculating someone's exact age at a past event, or figuring out age eligibility on a future cutoff date.
Why does it also show total days lived?
Total days is a simple, unambiguous count from birth date to the "as of" date, useful for things like age-in-days requirements (common for infants) or just curiosity about a round-number day milestone.
