Excel dates

I don't use Excel much and when I do it's mostly as a single page, glorified dynamic calculator (or to view what amounts to tabular data and lists sent by others). Dates are the part of the application I've most struggled with over the years.

Someone asked a question today about date calculations and was using functions I didn't even know existed. Excel Dates Help from Mr Excel was pretty informative and the site has a bunch of other archived categories. Worth a check anyway.
