How to translate the md-datepickers "Invalid Date" message?

like the topic says: in my project i have a md-datepicker, which in some cases (which are intended) shows "Invalid Date". Is there any possibility to translate or change this text?

Solution

Yes.

Actually, I'd got the same problem and "Invalid Date" should not be good at all. I thought it should be blank.

In my project, it happened when I enabled "md-open-on-focus" and I click on the input (not on icon or caret).

In addition, I was using Moment.js with the following configuration:

    $mdDateLocaleProvider.formatDate = function (date)
    {
        return moment(date).format('DD/MM/YYYY');
    };

As you can see, an invalid date like null or empty was formated and then returned.

Then, I've solved it by replacing it to this:

    $mdDateLocaleProvider.formatDate = function (date)
    {
        var tempDate = moment(date);
        return (tempDate.isValid() ? tempDate.format('DD/MM/YYYY') : '');
    };
