- * @name differenceInMonths

- * @summary Get the number of full months between the given dates.

- * @description
- * Get the number of full months between the given dates using trunc as a default rounding method.
- *
- * @param {Date|Number} dateLeft - the later date
- * @param {Date|Number} dateRight - the earlier date
- * @returns {Number} the number of full months
- * @throws {TypeError} 2 arguments required
- *
- * @example
- * // How many full months are between 31 January 2014 and 1 September 2014?
- * const result = differenceInMonths(new Date(2014, 8, 1), new Date(2014, 0, 31))
- * //=> 7
