 >>> date(2008, 1, 30) + monthdelta(1)  datetime.date(2008, 2, 29)

What would this loop would print?  for d in range(1, 32):  print date(2008, 1, d) + monthdelta(1) I have this funny feeling that arithmetic using monthdelta wouldn't always be intuitive.

Oh, certainly! But in the absence of "intuitive", I've found in the past that "standardised" is often better than nothing :-) (For example, I use Oracle's add_months function fairly often - it's not perfect, and not always intuitive, but at least it's well-defined in the corner cases, and fine for "normal" use).

Paul.
