Here you have the same question with Jquery UI Datepicker jQuery UI Picking a start and end date within range based on start date And a working example:

html

js

$(document).ready(function () {

    $("#dt1").datepicker({
        dateFormat: "dd-M-yy",
        minDate: 0,
        onSelect: function (date) {
            var dt2 = $('#dt2');
            var startDate = $(this).datepicker('getDate');
            var minDate = $(this).datepicker('getDate');
            dt2.datepicker('setDate', minDate);
            startDate.setDate(startDate.getDate() + 30);
            //sets dt2 maxDate to the last day of 30 days window
            dt2.datepicker('option', 'maxDate', startDate);
            dt2.datepicker('option', 'minDate', minDate);
            $(this).datepicker('option', 'minDate', minDate);
        }
    });
    $('#dt2').datepicker({
        dateFormat: "dd-M-yy"
    });
});
