Since Dates are really just doubles,  you don't really even need  the 
CDate() here, just Format(0,"dd mm yyyy").

That strikes me quite often when I'm doing date manipulation.  I've 
tried to see the reasoning behind that start date. So far, I can't 
see it at all. Can anyone come with  *any* logical reason?

Especially when you consider that Excel uses a more logical scheme 
where Day 1 is "1 Jan 1900"

Still in some ways Access is better than Excel which returns "O Jan 
1900" for Day 0 and an error for negative numbers :-)
