Does the result account for leap years?

Yes. The tool uses real calendar date math rather than a flat days-per-year estimate.

Can I use this for legal age verification?

It can help with calculation, but you should still verify against the exact policy or legal rule you need to follow.

Birthdate

Use ISO format (e.g., 1995-08-12).

Example
