+ * @name getOverlappingDaysInIntervals
+ * @category Interval Helpers
+ * @summary Get the number of days that overlap in two time intervals
+ *
+ * @description
+ * Get the number of days that overlap in two time intervals
+ *
+ * @param {Interval} intervalLeft - the first interval to compare. See [Interval]{@link docs/Interval}
+ * @param {Interval} intervalRight - the second interval to compare. See [Interval]{@link docs/Interval}
+ * @returns {Number} the number of days that overlap in two time intervals
+ * @throws {TypeError} 2 arguments required
+ * @throws {RangeError} The start of an interval cannot be after its end
+ * @throws {RangeError} Date in interval cannot be `Invalid Date`
+ *
+ * @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
