* Get the number of business day periods between the given dates.
|

|
|
* Business days being days that arent in the weekend.
|

|
|
* Like `differenceInCalendarDays`, the function removes the times from
|
||
|
|
* the dates before calculating the difference.
|
||
|
|
*
|
||
|
|
* @param {Date|Number} dateLeft - the later date
|
||
|
|
* @param {Date|Number} dateRight - the earlier date
|
||
|
|
* @returns {Number} the number of business days
|
||
|
|
* @throws {TypeError} 2 arguments required
|
||
|
|
*
|
||
|
|
* @example
|
||
|
|
* // How many business days are between
|
||
|
|
* // 10 January 2014 and 20 July 2014?
|
||
|
|
* var result = differenceInBusinessDays(
|
||
|
|
* new Date(2014, 6, 20),
|
||
|
|
* new Date(2014, 0, 10)
|
