+ * @name areIntervalsOverlapping
+ * @category Interval Helpers
+ * @summary Is the given time interval overlapping with another time interval?
+ *
+ * @description
+ * Is the given time interval overlapping with another time interval? Adjacent intervals do not count as overlapping.
+ *
+ * @param {Interval} intervalLeft - the first interval to compare. See [Interval]{@link https://date-fns.org/docs/Interval}
+ * @param {Interval} intervalRight - the second interval to compare. See [Interval]{@link https://date-fns.org/docs/Interval}
+ * @param {Object} [options] - the object with options
+ * @param {Boolean} [options.inclusive=false] - whether the comparison is inclusive or not
+ * @returns {Boolean} whether the time intervals are overlapping
+ * @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:
+ * areIntervalsOverlapping(
+ *   { start: new Date(2014, 0, 10), end: new Date(2014, 0, 20) },
+ *   { start: new Date(2014, 0, 17), end: new Date(2014, 0, 21) }
+ * )
+ * //=> true
+ *
+ * @example
+ * // For non-overlapping time intervals:
+ * areIntervalsOverlapping(
+ *   { start: new Date(2014, 0, 10), end: new Date(2014, 0, 20) },
+ *   { start: new Date(2014, 0, 21), end: new Date(2014, 0, 22) }
+ * )
+ * //=> false
+ *
+ * @example
+ * // For adjacent time intervals:
+ * areIntervalsOverlapping(
+ *   { start: new Date(2014, 0, 10), end: new Date(2014, 0, 20) },
+ *   { start: new Date(2014, 0, 20), end: new Date(2014, 0, 30) }
+ * )
+ * //=> false
+ *
+ * @example
+ * // Using the inclusive option:
+ * areIntervalsOverlapping(
+ *   { start: new Date(2014, 0, 10), end: new Date(2014, 0, 20) },
+ *   { start: new Date(2014, 0, 20), end: new Date(2014, 0, 24) }
+ * )
+ * //=> false
+ * areIntervalsOverlapping(
+ *   { start: new Date(2014, 0, 10), end: new Date(2014, 0, 20) },
+ *   { start: new Date(2014, 0, 20), end: new Date(2014, 0, 24) },
