FAQ
- How is the exact age calculated?
- The calculator counts full years first, then full months within the remaining partial year, then the leftover days. This mirrors the civil / legal convention for stating ages.
- What does "total days" mean?
- Total days is the raw number of calendar days between the birth date and the target date, including leap days.
- Is any data sent to a server?
- No. Everything runs entirely in your browser using the built-in JavaScript Date API; no data leaves your device.
