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 addmonths 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).

I think something like "date.add_months()" would be better than the proposed monthdelta. The monthdelta proposal suggests that addition is something well-defined and rigourous, which is not really the case here (for example, if you add a monthdelta and then substract it again, I'm not sure you always get back the original date).

Antoine.
