How can I enter dates in an Excel spreadsheet so that they appear in the form 00-00-0000?
I am using Excel 2008 for Macintosh. The program converts them to the form 00/00/00. If the dates are old enough, the program will leave them in the 00/00/0000 form. That would be close enough. If, however, there is a mixture of more recent dates and 19th century dates, then some are in the 00/00/0000 form while others are in the 00/00/00 form. 12/31/1920 and 12/31/2020 appear as the same date.
