Set dates in right calender is not working

rdcCalObj.leftCalendar.setDateFormat(“%m/%d/%Y”);
rdcCalObj.leftCalendar.setDate($(“#rdc-eff-date”).val()||null);
rdcCalObj.rightCalendar.setDateFormat(“%m/%d/%Y”);
rdcCalObj.rightCalendar.setDate($(“#rdc-eff-date”).val()||null);

Could you please, provide a complete demo or a demo link, where the problem can be reconstructed.
