When passing js Date objects to my ASP.NET Web Api controller, I always get null. I have tried passing strings, array of string, timespan - all those works, except Date. When inspecting the request, the date is passed like this: 

date:"2014-03-13T15:00:00.000Z"

In angular:

$http({ 
    method: 'get', 
    url: 'api/stuff', 
    params: {
       date: new Date()
    }
);

In my ApiController:

public IEnumerable<StuffResponse> Get(
    [FromUri] DateTime? date
){ ... }

What is the correct way to pass dates?

The formatting of the date in your Javascript is not compatible with .NET DateTime parsing. See here for valid formats.

either use a different format like @Rondles is saying or just take it in as a string and parse it using DateTime.Parse –  SnareHanger Mar 3 '14 at 14:37
    
when sending the js date through postdata, .NET manages to create a DateTime - so I guessed it would work when using get and params also.. –  Trylling Mar 3 '14 at 14:43
    
The format of the date ("2014-03-13T15:00:00.000Z") is exactly the same for $http post data and get params, but the ApiController doesn't manage to recognize the string as a DateTime for get params. –  Trylling Mar 4 '14 at 6:35
    
I would suggest that you try SnareHangers approach and before you send it, convert it into a .NET recognised format. If it still doesn't work then you have a different problem. If it does work then the current formatting combined with this type of AJAX request is causing the issue. –  BenM Mar 4 '14 at 7:06

This works for me:

$http({ 
    method: 'get', 
    url: 'api/stuff', 
    params: {
       date: $filter('date')(new Date(), "yyyy-MM-dd HH:mm:ss")
    }
);
