* @summary Get the number of days that overlap in two time intervals
|
|

|
|
* @description
|
|
* Get the number of days that overlap in two time intervals. It uses the time
|
|
* between dates to calculate the number of days, rounding it up to include
|
|
* partial days.
|
|
*
|
|
* Two equal 0-length intervals will result in 0. Two equal 1ms intervals will
|
|
* result in 1.
|
|
*
|
|
* @param intervalLeft - The first interval to compare.
|
|
* @param intervalRight - The second interval to compare.
|
|
* @param options - An object with options
|
|
*
|
|
* @returns The number of days that overlap in two time intervals
|
|
*
|
|
* @example
|
|
* // For overlapping time intervals adds 1 for each started overlapping day:
|
|
* getOverlappingDaysInIntervals(
|
|
* { start: new Date(2014, 0, 10), end: new Date(2014, 0, 20) },
|
|
* { start: new Date(2014, 0, 17), end: new Date(2014, 0, 21) }
|
|
* )
|
|
* //=> 3
|
|
*
|
|
* @example
|
|
* // For non-overlapping time intervals returns 0:
|
|
* getOverlappingDaysInIntervals(
|
|
* { start: new Date(2014, 0, 10), end: new Date(2014, 0, 20) },
|
|
* { start: new Date(2014, 0, 21), end: new Date(2014, 0, 22) }
|
|
* )
|
|
* //=> 0
