i have a calender control which gives me date in "dd/mm/yyy" format.

I am able to calculate age in years...i want age + months..

Please tell me how do i go about it.....

here is my logic to calculate age :

myDOB = txtDate.value.split('/');
myDate = myDOB[0];
myMonth= myDOB[1];
myYear = myDOB[2];

var age;
var now = new Date();
var todayDate = now.getDate();
var todayMonth = now.getMonth();
var todayYear = now.getYear();
if(myDate <= todayDate)
{
if(myMonth <= todayMonth)
age = todayYear-myYear;
else if(myMonth>todayMonth)
age = todayYear - myYear-1;
}
else if(myDate > todayDate)
{
if(myMonth < todayMonth)
age = todayYear - myYear -1;
else
age = todayYear - myYear -1;
}
alert(age);

Please tell me how do i calculate months by this logic

try like this

if(myMonth <= todayMonth)
age = todayYear-myYear;
else if(myMonth>todayMonth)
age = todayYear - myYear-1;
months = 12-(mymonth-todaymonth)
