title: Customize the Error Message MVC for an invalid DateTime in ASP.NET MVC4
body: <p>I am having trouble specifying the error message for the validation of a DateTime input value using data annotations in my model. I would really like to use the proper DateTime validator (as opposed to Regex, etc).</p>
  
  <pre><code>[DataType(DataType.DateTime, ErrorMessage = "A valid Date or Date and Time must be entered eg. January 1, 2014 12:00AM")]
  public DateTime Date { get; set; }
  </code></pre>
  
  <p>I still get the default date validation message of "The field Date must be a date."</p>
  
  <p>Am I missing something?</p>
