Age Calculator
Find your exact age in years, months and days — plus how long until your next birthday.
FAQ
How is age calculated?
We count full years, then full months, then remaining days between your date of birth and the comparison date — the same way you'd count it by hand on a calendar.
Is my birth date stored anywhere?
No. The calculation runs entirely in your browser using JavaScript — nothing is sent to a server or saved.
Can I calculate age on a future or past date?
Yes — change "Calculate age as of" to any date to see age at that point, useful for eligibility rules, legal ages, or planning ahead.
