+ * @description
+ * Get the number of calendar weeks between the given dates.
+ *
+ * @param {Date|Number} dateLeft - the later date
+ * @param {Date|Number} dateRight - the earlier date
+ * @param {Object} [options] - an object with options.
+ * @param {Locale} [options.locale=defaultLocale] - the locale object. See [Locale]{@link https://date-fns.org/docs/Locale}
+ * @param {0|1|2|3|4|5|6} [options.weekStartsOn=0] - the index of the first day of the week (0 - Sunday)
+ * @returns {Number} the number of calendar weeks
+ * @throws {TypeError} 2 arguments required
+ * @throws {RangeError} `options.weekStartsOn` must be between 0 and 6
+ *
+ * @example
+ * // How many calendar weeks are between 5 July 2014 and 20 July 2014?
+ * const result = differenceInCalendarWeeks(
+ *   new Date(2014, 6, 20),
+ *   new Date(2014, 6, 5)
+ * )
+ * //=> 3
+ *
+ * @example
+ * // If the week starts on Monday,
+ * // how many calendar weeks are between 5 July 2014 and 20 July 2014?
+ * const result = differenceInCalendarWeeks(
+ *   new Date(2014, 6, 20),

+ *   { weekStartsOn: 1 }
