Very simple. Just look at the difference.

dt2-dt1 = 2.5    =>  two and a half days past by...

Sure, just subtract 1 from the other.  Like This

function ElapsedDays(D1, D2: TDateTime): integer;
begin
  Result := Round(abs(D1 - D2));
end;

Am sitting at work right now. So I check my eMails and EE every hour. It's good that my boss works two streets from here...  :-)

Hi Heath, hmmm. If I would have written a little function (like you did), you would have probably been faster than I. So I'm sorry for taking the points away...    :-)
