HTML

<label for="checkin">Please select Check-In date</label>
<input type="text" class="datepicker" id="checkin" name="checkin" />
<br />
<label for="b_checkin_day">Check-In day</label>
<input type="text" id="b_checkin_day" name="b_checkin_day" readonly />
<br />
<label for="b_checkin_day">Check-In month and year</label>
<input type="text" id="b_checkin_month" name="b_checkin_month" readonly />

JavaScript

$(function () {
    $('#checkin').datepicker({
        buttonText: 'Choose a check-in day',
        buttonImage: 'images/calendar_icon.png',
        buttonImageOnly: false,
        dateFormat: 'mm/dd/yy',
        onSelect: function (dateText) {
            var objDate = new Date(dateText);
            var chkinDate = $.datepicker.formatDate('dd', objDate);
            var chkinMonth = $.datepicker.formatDate('M yy', objDate);
            $('#b_checkin_day').val(chkinDate);
            $('#b_checkin_month').val(chkinMonth);
        }
    });
});
