Remarks

This property allows a 2-digit year to be properly translated to a 4-digit year. For example, if this property is set to 2029, the 100-year range is from 1930 to 2029. Therefore, a 2-digit value of 30 is interpreted as 1930, while a 2-digit value of 29 is interpreted as 2029.

The initial value of this property is derived from the settings in the regional and language options portion of Control Panel. However, that information can change during the life of the AppDomain. The Calendar class does not detect changes in the system settings automatically. If the calendar is not supported in the regional and language options, the initial value of this property is the default value defined by the Calendar class.

Your application should set this value to 99 to indicate that 2-digit years are to be taken literally. For example, if this property is set to 99, the 100-year range is from 0 (not a valid value for most calendars) to 99. Therefore, a 2-digit value of 30 is interpreted as 30.
