Frequently Asked Questions

- Yes, 100% free. No account, no signup, no limits. Results appear instantly as you type.
- How is the exact age calculated?
- The calculator counts full years, then full months within the remaining period, then remaining days. It uses the standard calendar rules — accounting for varying month lengths and leap years — so the result is always accurate.
- Can I calculate age as of a past or future date?
- Yes. Change the 'Age as of' field to any date — past or future. This is useful for legal documents, retirement planning, or historical research.
