store the number of year in a variable : yearAge
use :

function calcage() {
				var vdob = new Date(document.getElementById("dateofbirth").value);				
				var vcurrentTime = new Date();
				var vyear = vcurrentTime.getFullYear();
				var ageInMilliseconds = vcurrentTime.getTime() - vdob.getTime();
                                var ageInYear = Math.floor(ageInMilliseconds / (1000 * 60 * 60 * 24 * 365.25));
                                var ageInYearMillisecond = ageInYear * 1000 * 60 * 60 * 24 * 365.25
                                var months = Math.floor((ageInMilliseconds - ageInYearMillisecond)/(1000 * 60 * 60 * 24 * 29.5));
				document.getElementById("age").value = ageInYear + ' years' + " and " + months;

I tried but the formula does not. FOr example the persons birthday is on 3/24/1999 so today he is exactly 15 years 9 month old, if I shift the date to 3/25/1998 then it is still shows me 15 years and 6 month event though his 15 years and 9 month will be tomorrow
