Earlier versions of Windows interpret two-digit years based on certain defaults: Specifying two-digit years for the year argument are read as per user-defined desktop settings in Windows 98 or Windows 2000 systems, wherein the default settings read values from 0 to 29 as the years 2000 to 2029 and values from 30 to 99 as the years 1930 to1999 and for all other years the four-digit year is used.

The Function will return an error in the case of any argument value being outside the range -32,768 to 32,767 or in case the final date (after evaluating the 3 arguments) falls outside the valid date range. When values supplied for an argument exceeds its acceptable range, the increment will be to the next applicable unit, for example, supplying 14 as the value for the month argument will increment to the second month (February) of the next year.
