Why do you want to store the persons age in the database rather than their date of birth?

Age is a little more complex than you might think! See here: Working with Age: it's not the same as a TimeSpan![^]

hi!...can i use javascript to get age...?
Rambo_Raja 18-Jun-13 3:04am
code in javascript is as: function ageCount() {
var date1 = new Date();
var dob= document.getElementById("dob").value;
var date2=new Date(dob);
var pattern = /^\d{1,2}\/\d{1,2}\/\d{4}$/; //Regex to validate date format (dd/mm/yyyy)
if (pattern.test(dob)) {
var y1 = date1.getFullYear(); //getting current year
var y2 = date2.getFullYear(); //getting dob year
var age = y1 - y2; //calculating age
document.write("Age : " + age);
return true;
} else {
alert("Invalid date format. Please Input in (dd/mm/yyyy) format!");
return false;

You can do it in JS, but you would need code very similar to that in the C# link I gave you.

BTW: If you want a JavaScript solution in future, you should put that in your question rather than C#...
