How to read your result
A worked example
Someone born on 15 June 2000 is 25 years, one month and five days old on 20 July 2025.
How it is calculated
Completed anniversaries and months are counted before the remaining days. Total days lived are calculated separately using civil dates.
Common mistakes and limitations
A 29 February birthday uses 28 February in non-leap years. Administrative or legal rules may use a different convention.
