You should implement IValidatableObject and take of the Require. Then the validation on the server side will do the job, something like:

public class MyModel : IValidatableObject
{
  public int Year { get; set; }
  public int Month { get; set; }
  public int Day { get; set; }

  public IEnumerable Validate(ValidationContext validationContext)
  {
      if (/*Validate properties here*/) yield return new ValidationResult("Invalid Date!", new[] { "valideDate" });
  }
}

For client side validation you need to implement your own function, and prompt the error to the user somehow.

EDIT: Given that you still need client side validation, you should do something like this:

$("form").validate({
    rules: {
        Day: { required: true },
        Month : { required: true },
        Year : { required: true }
    },
    groups: {
        Date: "Day Month Year"
    },
   errorPlacement: function(error, element) {
       if (element.attr("id") == "Day" || element.attr("id") == "Month" || element.attr("id") == "Year") 
        error.insertAfter("#Day");
       else 
        error.insertAfter(element);
   }
});
