    minDate: new Date((currentYear - 1), 12, 1),
    dateFormat: 'dd/mm/yy',
    maxDate: new Date(currentYear, currentMonth, currentDay)
  });
  $("#todate").datepicker({
    minDate: new Date((currentYear - 1), 12, 1),

试试这个，

$(function() {
      var currentYear = (new Date).getFullYear();  
      $('#fromdate').datepicker({
        minDate: 0,
        dateFormat: 'dd/mm/yy',
        maxDate: new Date((currentYear + 1), 12, 1),
        onSelect: function(selectedDate) {

            // Start Date
            var startDate = $(this).datepicker('getDate');
            $('#todate').datepicker('option', 'minDate', startDate);
            $('#todate').datepicker('setDate', startDate);

            // End Date
            var enddate = $(this).datepicker('getDate');
            enddate.setDate(enddate.getDate()+ 6);
            $('#todate').datepicker('option', 'maxDate', enddate);
      }});

      $('#todate').datepicker({
        minDate: 0,
        dateFormat: 'dd/mm/yy',
        maxDate: '+6'
    });

});
