I'm new to python core development, and I've been advised to write to python-dev concerning a feature/patch I've placed at http://bugs.python.org/issue5434, with Rietveld at http://codereview.appspot.com/25079. Without having looked at the code, I wonder whether you've looked at python-dateutil.   I believe its relativedelta type does what you propose, plus much more, and it has the advantage of being widely used and tested.

The key thing missing (I believe) from dateutil is any equivalent of monthmod.

Hmm, it might be possible via relativedelta(d1,d2), but it's not clear to me from the documentation precisely what attributes/methods of a relativedelta object are valid for getting data out of it.

I do agree, though, that any proposal to extend the Python datetime module should at least be informed by the design of the dateutil module.
