Description

Call MonthSpan 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. Unlike the MonthsBetween function, which does not report fractional "months", MonthSpan reports incomplete months as a fraction of an entire month.
