I think it would make more sense to treat days separately, rather than trying to fit it into this macro (and thus giving all other properties the same behavior, even though it doesn't make sense there).

We could then also explicitly check for a false value, rather than "" === (string)false, as what is done now.

I've created a separate macro for handling days property.

But I'm not sure if it's the best way to solve this problem.
