Description
Returns the approximate number of months between two specified TDateTime values.
Call MonthsBetween to obtain the difference, in months, between two TDateTime values. Because months are not all the same length, MonthsBetween returns an approximation based on an assumption of 30.4375 days per month. Fractional months are not counted. Thus, for example, MonthsBetween reports the difference between February 1 and March 1 as 0.
MonthsBetween always returns a positive result and therefore the parameter values are interchangeable.
