            dateFormat: 'dd-M-yy',
            yearRange: '-90:-15'

        });

At year dropdown calender filled with range 1922-1997 and showing 1922 as initial value.

But still when I pick a date from this calender , it shows 2012 in textbox field, why?.

Answer 1

 $("#dob").datepicker("option", "defaultDate", '-90y');

Secondly one can also place defauleDate as below

     $("#dob").datepicker({
            changeMonth: true,
            changeYear: true,
            dateFormat: 'dd-M-yy',
            yearRange: '-90:-15',
            defaultDate:'-90y'

        });
