- In the Customize Regional Options dialog box, click the Date tab to specify any changes you want to make to the short date and the long date.
- If you do not see the format you want in the Short date or Long date boxes, use the following guidelines:
- To display single-digit numbers without a leading zero, type d for the day setting, type y for the year setting, and type M for the month setting.
- To display leading zeros with single-digit numbers, type dd for the day setting, type yy for the year setting, and type MM for the month setting.
- To display the last two digits of the year, type yy for the year setting.
- To display four digits for the year, type yyyy for the year setting.
- To display abbreviations for the day or month, type ddd for the day setting and type MMM for the month setting.
- To display the full name of the day or month, type dddd for the day setting and type MMMM for the month setting.
- To display additional text, type single quotation marks (') around text.
NOTE: Type an uppercase M for the month setting. The lowercase m is used for the minute setting.
- To specify how your computer interprets two-digit years, on the Date tab, under When a two-digit year is entered, interpret it as a year between, type or click the year that you want to configure this setting to end at.
This feature has a 100-year span (the default span is 1930 to 2029). Four-digit years are not affected by this option. A program that uses this option to interpret two-digit years considers the years between (and including) 30 and 99 to be preceded by 19, and years between (and including) 00 and 29 to be preceded by 20. For example, 99 is interpreted as 1999 and 01 is interpreted as 2001.
NOTE: Not all programs use this option. If the program you are using does not correctly interpret two-digit years, consult the documentation or manufacturer of that program.
