Frequently Asked Questions
Why doesn't this show my age in a single decimal number?
A breakdown of years, months and days is more precise and easier to use for official forms than a rounded decimal age.
Can I calculate age as of a future or past date, not just today?
Yes — change the "Calculate age as of" field to any date, which is useful for checking age eligibility on a specific date.
