Hi @jlsalvador

What is this PR about? the class you are adding is not including in the css

Hello @gschammah

On our website we need to add a new class to differ the days between the months. So... I added the new class.

Before:

After:

If you like, I can add "pickadate-another-month" to the CSS provided by angular-pickadate with a lighter gray color, like a demo.

+1 to this.
And since the module structure changed, you need to add the new class using the new "date" object:
if (date.date.getMonth() !== scope.currentDate.getMonth()) date.classNames.push('pickadate-another-month');
