Am new at this. I have created custom fields called Date Left and Date Reinstated in the dd/mm/yyyy format. When I try to import the data, days bigger than 12 are shown as errors, and up to 12 come in, but as mm/dd/yyyy. We have already imported into built-in date fields successfully using dd/mm/yyyy. Am using CiviCRM 4.6.2 on Joomla!3.4.1.
