Hi Matt,
Thank you for bringing this to our attention... We use the same control that DNN uses (DotNetNuke Date Picker Control) so I am not sure if this is an issue with that control or the older version of DNN you are running etc... I do know that we really do not control the code for that specific field type very much though.
You might review this Dynamic Forms demonstration that covers Date Fields... I often like to use the jQuery Date Picker instead of using the standard method that the module offers.
