Hi!
It will be extremely useful to set Days of the Week and Months in different languages (spanish in my case).
I dont think that it should be that hard, the interface should be something like this:

<DatePicker
  hintText="Portrait Dialog"
  daysName={['Sunday', 'Monday', ...]}
  monthsName={['January', 'February', ...]}
  />

I believe that the value outstands the complexity of implementing this 😄

Thanks!
