Century interpretation for Year 2000

User Configuration\Administrative Templates\System

Description

Determines how programs interpret two-digit years, and prevents users from changing this option.

This policy also disables the When a two-digit year is entered, interpret it as a year between spin box in the Calendar section of the Date tab in Regional Options in Control Panel. As a result, users cannot change the interpretation of two-digit years while this policy is in effect.

This policy specifies the largest two-digit year interpreted as being preceded by 20. All numbers less than or equal to the specified value are interpreted as being preceded by 20. All numbers greater than the specified value are interpreted as being preceded by 19.

For example, the default value, 2029, specifies that all two-digit years less than or equal to 29 (00 to 29) are interpreted as being preceded by 20, that is 2000 to 2029. Conversely, all two-digit years greater than 29 (30 to 99) are interpreted as being preceded by 19, that is, 1930 to 1999.

Note

This policy only affects the programs that use this Windows feature to interpret two-digit years. If a program does not interpret two-digit years correctly, consult the documentation or manufacturer of the program.

This policy applies only to localized Gregorian calendars.

This policy was documented incorrectly on the Explain tab in Group Policy for Windows 2000. The Explain tab fails to mention that this policy disables an option on the Date tab.
