Davemi ToolsAge Calculator
Calculate exact age in years, months, and days from a birth date.
Frequently Asked Questions
Can I calculate age as of a different date, not just today?
Yes — change the "As of" date to calculate exact age at any point in time, e.g. for a specific event or eligibility cutoff.
How is the exact years/months/days figure calculated?
It counts full calendar years, then full months within the current year, then remaining days — the same method used on official age-verification forms.
Is my birth date stored or sent anywhere?
No. The calculation happens entirely in your browser — nothing is saved or transmitted.
