jQuery Datepicker minDate not working

Question

I would expect the following would have the date range to start from 65 years ago and end at 18 years ago. Instead, minDate number is ignored, and set to 10 years prior to end date. No difference whatever I put as value in minDate.

$(function() {
    $("#datepicker").datepicker({
        changeMonth: true,
        changeYear: true,
        minDate: "-65y",
        maxDate: "-18y"
    });
});​

Answer 1

This works for me;

$("#txt_birthdate").datepicker({
  yearRange: "-100:-18",
  changeMonth: true,
  changeYear: true,
  maxDate: new Date()
});

Answer 2

You can use yearRange option for that;

$('#datepicker').datepicker({
    changeMonth: true,
    changeYear: true,
    yearRange: "-65y:-18y"
});
