Also, what format are the dates in?
Sometimes the unreliable piece of junk aka as Excel makes confusion
between the European and the American format: for example, when
reading the date '20/1/2007' it might not recognize it as European
format, and return an error because the calendar does not have 20
months.

Which date function? If you are using things like EDATE then you need to
make sure the ATP (Analysis ToolPak) is installed and selected under
toolsadd-ins, you might need the installation CD for this.
