Does this account for leap years?

Yes. The calculation uses calendar arithmetic (not 365.25 days), so leap years are exact.

Can I calculate the age of something other than a person?

Yes — use it for any date. Enter the start date and the tool computes the elapsed time precisely.

Calendar months are counted, not 30-day intervals. This matches how age is stated legally and medically.
