I found an answer at the bottom of this page in comments section (which is now offline).

By the way, here is how to calculate age in years (only) from DOB without needing to account for leap years:
With a slight correction by Fine-Wei Lin, the code reads
private function getYearsOld(dob:Date):uint {
var now:Date = new Date();
var yearsOld:uint = Number(now.fullYear) - Number(dob.fullYear);
if (dob.month > now.month || (dob.month == now.month && dob.date > now.date))
{
yearsOld--;
}
return yearsOld;
}
This handles most situations where you need to calculate age.

var userDOB : Date = new Date(year,month-1,day);
var today : Date = new Date();
var diff : Date = new Date();
diff.setTime( today.getTime() - userDOB.getTime() );
var userAge : int = diff.getFullYear() - 1970;

Here's a one-liner:
int( now.getFullYear() - dob.getFullYear() + (now.getMonth() - dob.getMonth())*.01 + (now.getDate() - dob.getDate())*.0001 );

I found a few problems with the top answer here. I used a couple of answers here to cobble together something which was accurate (for me anyway, hope for you too!)
private function getYearsOld(dob:Date):uint
{
var now:Date = new Date();
var age:Date = new Date(now.getTime() - dob.getTime());
var yearsOld:uint = age.getFullYear() - 1970;
return yearsOld;
}

You could also do it roughly the same as discussed here: (translated to AS3)
var age:int = (new Date()).fullYear - bDay.fullYear;
if ((new Date()) < (new Date((bDay.fullYear + age), bDay.month, bDay.date))) age--;

Here is a little more complex calculation, this calculates age in years and months. Example: User is 3 years 2 months old.
private function calculateAge(dob:Date):String {
var now:Date = new Date();
var ageDays:int = 0;
var ageYears:int = 0;
var ageRmdr:int = 0;
var diff:Number = now.getTime()-dob.getTime();
ageDays = diff / 86400000;
ageYears = Math.floor(ageDays / 365.24);
ageRmdr = Math.floor( (ageDays - (ageYears*365.24)) / 30.4375 );
if ( ageRmdr == 12 ) {
ageRmdr = 11;
}
return ageYears + " years " + ageRmdr + " months";
}
