Lee prefers a date format that uses periods, such as 9.29.11. He wonders if there is a way to create such a format and if that format can be set as the default date format used by Excel.
Defining the date format in Excel is easy. Just follow these steps:
Figure 1. The Number tab of the Format Cells dialog box.
That's it; you now have a format set to display dates you want. If you want the format to be the default for all dates, then you are going to have to make a change in the Regional Settings of Windows itself. (Excel draws its default from these settings.) The exact way you do this varies depending on the version of Windows you are using, but in general there is a choice in the Windows Control Panel that allows you to specify regional settings. All you need to do is modify those settings to reflect the date format you want to use. The change will affect not only the display of numbers in Excel, but in other Windows-compliant programs, as well.
