I am trying to subtract two dates in excel but I keep getting weird results... My dates are formatted like this: 8/11/2010 I am using TODAY() to return the current date. Then I want to compare that to see how many days have passed since a given date. So my formula is this: =TODAY()-D2 Now, it seems to kind of work because the result I get is 1/30/1911. 30 days is the correct answer! But why am I getting the full date?? How can I fix this? And why the heck is it saying 1911 - on another computer I tried it says 1/30/1900... ??
