HKCU\Control Panel\International

Data type Range Default value
REG_SZ Date format For U.S. English: M/d/yy


Specifies the format used to display dates in short date (numeric) format, such as 6/5/69.

Change method

To change the value of this entry, double-click Regional Options in Control Panel. Click the Date tab, and then make a selection from the Short date format drop-down list box.

Note Image Note

Regional Options in Control Panel links the sDate and sShortDate entries. This ensures the date separator and the date format are synchronized. For example,

sDate  sShortDate  Meaning
/ M/d/yy 6/5/69

Setting sTime and sTimeFormat independently in the registry can result in conflicting values. To repair these settings, use Regional Options in Control Panel.

Setting only one value in the registry might not change the date as it appears in applications, because an application can read either sDate or sShortDate.
