<DateTime1>.monthsBetween(<DateTime2>)

<Date1>.monthsBetween(<Date2>)

Returns the Integer number of months between DateTimes or between Dates. The month and year portions of the date data are subtracted to calculate the number of elapsed months. The day portions are ignored. If the month and year portions are the same, the result is zero. This function returns a positive number if <DateTime2> is later than <DateTime1>.
