OL98: Weekday Is Wrong for Dates More than 30 Years Ago

MORE INFORMATION

When you type a two-digit date in some Outlook fields, Outlook applies an internal calculation to see if the date is more than 30 years in the past. If the date is more than 30 years in the past, Outlook interprets the two- digit date as 20XX instead of 19XX. Outlook makes its internal calculation based on the first day of the current month and year of your computer system date. For example, if the current date for your computer is 12/17/1996 and you enter the date 1/1/60 into a date field, Outlook subtracts 1/1/60 from 12/1/1996. Because the difference is more than 30 years, Outlook uses the date 1/1/2060 for the field.

NOTE: Not all Outlook Date fields use this internal calculation. Some fields, such as Birthday and Anniversary fields, do not apply the calculation and always evaluate two digit years as if they were in the past.

To see the 30-year behavior, follow these steps:

1. On the Outlook Bar, click Tasks to open your Tasks folder.
2. On the Actions menu, click New Task to open a new untitled task.
3. In the Due box, type 1/1/50, and then press TAB.
4. Click the arrow to the right of the Due box.
5. Note that the Calendar Picker reflects the year 2050.
