We can change daetpicker year range from Serenity.CorLib.js

$.datepicker.setDefaults({
            dateFormat: (order == 'mdy' ? 'mm' + s + 'dd' + s + 'yy' :
                (order == 'ymd' ? 'yy' + s + 'mm' + s + 'dd' :
                    'dd' + s + 'mm' + s + 'yy')),
            buttonImage: Q.resolveUrl('~/Content/serenity/images/datepicker.png'),
            buttonImageOnly: true,
            showOn: 'both',
            showButtonPanel: true,
            changeMonth: true,
            changeYear: true,
            yearRange: "c-30:c+5"
        });

In above code we were set yearRange : "c-30:c+5" So, now date picker show date range 1987 - 2022 (considering 2017 is current year).
