The end user will only know there is an error if you reformat the date to say something like "March 5, 2010." We are essentially filling out federal forms which require the date to be entered MM/DD/YYYY and council advised that the user must be presented with what is essentially an electronic version of the form for validation. That means they have to be presented with a format, that if they didn't read the instructions, would be wrong still. We already determined that the users were not reading the format prompts so this doesn't actually work.
