+ * @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 unless `inclusive` is set to `true`.
+ *
+ * @param intervalLeft - The first interval to compare.
+ * @param intervalRight - The second interval to compare.
+ * @param options - The object with options
+ *
+ * @returns Whether the time intervals are overlapping
+ *
+ * @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) },
+ *   { inclusive: true }
+ * )
+ * //=> true
