If you change your browser settings to use a different language, the date input will be localized to that language.

I'd love to have a little more control over this. Perhaps adding:

  lang="fr"

to the input element or even the <html> tag, could localize the input?

The date picker runs from 01-01-0001 to 13-9-275760. Is this upper limit due to accuracy?

DateComponents.h

  static inline double maximumDate() 
  { return  8640000000000000.0; } // 275760-09-13T00:00Z
