I have created a simple application build using asp.net MVC and SQL Server targeting the azure platform. My question is around date formatting. I have added a date picker which correctly uses dd/mm/yyy format. however when I pick the date I get the following validation error.

The project was build using database first. here is a screenshot of the property for that data item:

Where do I change the validation to accept dd/MM/yyyy. Also is there a way to set it so if there is a user in the US it will change date picker and validation to MM/dd/yyyy?
in both situations the date will be saved to the database as standard yyyy-MM-dd hh:mm:ss
