      _locale: [...],
      _d: Fri Jan 02 2015 00:00:00 GMT-0600 (CST) }
  ],
  [...]
]
*/

It's like monthBusinessWeeks(), but this method will include weekends on it's response.

The objects returned by functions are momentjs objects (except isBusinessDay) so you can handle it with moment native functions.
