I have a problem with a dataset in which I have 3 sets of dates that were apparently entered as text, instead of as dates and look like mm/dd/yy. When I formatted each column to be date mm/dd/yyyy, no change takes place. How do I change 12,000 dates to say mm/dd/2001 instead of mm/dd/01? I tried replace ??/??/01 with ??/??/2001 and that didn't work. Thanks in advance!
