Changing the way ArcMap calculates two-digit years on Windows XP

You can change the way ArcMap displays date formats by setting date format options within the Regional and Language settings of your computer.

Steps:

1. Click the Start button in Windows XP.
2. Click Control Panel.
3. Click Regional and Language Options.
4. Click the Regional Options tab.
5. Click the Customize button.
6. Click the Date tab.
7. Under Calendar, specify the 99-year range you want your system to use when a two-digit year is entered. When you type in the end year, the start year is calculated.

   When you enter a two-digit year, dates 00 through 29 are automatically assigned to the 21st century (year 2000) and 30 through 99 are assigned to the 20th century (year 1900).

8. Click OK.
9. Click OK on the Regional and Language Options dialog box.

Note:

When you want to enter a year earlier or later than the date range on the Regional Options tab, you need to enter a four-digit year.
