Microsoft Year 2000 Readiness Disclosure & Resource Center
Updating Your Date Settings for the Year 2000
In anticipation of the new millennium, you can change the date settings in your operating system to help avoid date mistakes in your Microsoft Office software. For example, you can check the accuracy of dates as you enter them if the format for the date displays four-digit instead of two-digit years. In other words, by changing your operating system date settings, when you enter 2/23/01, you can force your Office applications to display the date as 2/23/2001.

The next release of OfficeùOffice 2000ùuses a new feature of Windows« 98 (and Windows 2000, which is yet to be released) that addresses the entry of dates. Currently, when you enter a two-digit year in a date, Microsoft Excel, for example, assumes that the year falls within the 21st century if the digits are in the range 00 to 29 (2000 through 2029). If you enter a number from 30 to 99, the dates are assumed to fall within the 20th century (1930 through 1999). With Windows 98 you can change the way two-digit years are interpreted; that is, instead of interpreting two-digit years between 1930 and 2029, you can set the shortcut time period (100 year window) to 1950 to 2049.

Change the Default Date Format to Display Four-Digit Years

  1. On the Windows Start menu, point to Settings, and then click Control Panel.
  2. Double click Regional Settings (or Regional Options if you are using Microsoft Windows 2000), and then click the Date tab.
  3. In the Short Date Style list, click a format that uses four digits for the year ("yyyy").

Change the Way Two-Digit Years are Interpreted

This procedure changes the way two-digit years are interpreted by some applications running under Windows 98 and Windows 2000.

  1. On the Windows Start menu, point to Settings, and then click Control Panel.
  2. Double click Regional Settings (or Regional Options if you are using Microsoft Windows 2000), and then click the Date tab.
  3. In the When a two-digit year is entered, interpret as a year between box, change the upper-limit for the century.
    As you change the upper-limit year, the lower-limit year automatically changes.

Note   Both Access 97 and Visual Basic« for Applications for Office 97 are affected by the changes to the two-digit year interpretation. Other Office 97 applications are not affected by this procedure. This procedure will affect other applications, however, such as Office 2000.
