<script>
    function dateYear(){
        var d = new Date();
                var year = d.getFullYear();
                return year;
    }
    $(function() {
        $( "#id_birth_date" ).datepicker({ dateFormat: 'yy-mm-dd' });

        //how can I get the selected year?
    });

</script>

<input type="text" name="birth_day" id="bd">
<input type="text" name="age" id="ag">

Do you mean:

$(function() {
     $("#id_birth_date").datepicker({
           onSelect: function(dateText, inst) {
              var startDate = new Date(dateText);
              var selectedYear = startDate.getFullYear(); // selected year
           }
     });
});

It will be possible.. after selecting date from datepicker

You will get property of datepicker1.year which will help you get year

Or

After retrieving date into string use Convert.Toint32(strDate1)-Convert.Toint32(strDate2) ;

..Try it...Otherwise post you code,...

You should be able to utilize the val() function.

The selected answer has a problem: the dateText may not be parsed because it depends on text which can be customised. Below is the enhanced accurate answer. Otherwise you will end up using an undefined date object:

$(function() {
     $("#id_birth_date").datepicker({
           onSelect: function(dateText, inst) {
              var startDate = new Date(inst.selectedYear, inst.selectedMonth, inst.selectedDay);
              var selectedYear = startDate.getFullYear(); // selected year
           }
     });
});
