You can use onselect event to get dates.

In your case, $(#date2) represents the next birthday

$('#date1').datepicker({
   onSelect: function(dateText, inst) { 
       var d1=new Date(dateText);
       // get date from other text field
       var d2=new Date($('#date2').val());
       // d2 -d1 gives result in milliseconds
       // calculate number of days by Math.abs((d2-d1)/86400000, as 24*3600*1000 = 86400000
       // and populate it to some text field #textfield
       $('#textfield').val((Math.abs((d2-d1)/86400000)));
   }
});
