Claudius,
Hvis du kigger på
http://javascript.internet.com/calculators/age-calculator.html er løsningen næsten skrevet for dig :) så lad os da blive \"inspireret\" og nappe den til dig.
Essensen er kopieret her - Scriptet kan ufravigeligt en del mere end du har brug for, men det er vist nemmere at barbere af end at kode noget fra bunden, ikke ?

<!-- THREE STEPS TO INSTALL AGE CALCULATOR:
1. Copy the coding into the HEAD of your HTML document
2. Add the onLoad event handler into the BODY tag
3. Put the last coding into the BODY of your HTML document -->
<!-- STEP ONE: Paste this code into the HEAD of your HTML document -->
