monthBusinessWeeks()

Retrieve an array of arrays, these arrays are the representation of a business weeks and each week (array) have it own business days (Monday to Friday). There could be the case that one week (array) have less than 5 days, this is because the month started on the middle of the week, for example: the first week of January 2015 just have two days, Thursday 1st and Friday 2nd. Each day in the week arrays are moment objects.

// Business weeks in month January 2015
moment('01-01-2015', 'DD-MM-YYYY').monthBusinessWeeks()

/*
[ [ { _isAMomentObject: true,
      _i: '01-01-2015',
      _f: 'DD-MM-YYYY',
      _isUTC: false,
      _pf: [...],
      _locale: [...],
      _d: Thu Jan 01 2015 00:00:00 GMT-0600 (CST) 
    }, { _isAMomentObject: true,
      _i: '01-01-2015',
      _f: 'DD-MM-YYYY',
      _isUTC: false,
      _pf: [...],
      _locale: [...],
      _d: Fri Jan 02 2015 00:00:00 GMT-0600 (CST) }
  ],
  [...]
]
*/

monthNaturalWeeks()

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.

businessDiff()

Calculate number of business days between dates.

var diff = moment('05-15-2017', 'MM-DD-YYYY').businessDiff(moment('05-08-2017','MM-DD-YYYY'));
// diff = 5
