While trying to provide my first answer, I thought of suggesting
this, but there doesn't appear to be a simple way of doing it.
It looked like the following was the best I could do (where 'x'
is a object):

   z = datetime.datetime(x.year, x.month,

I just found timetuple(), which means this could be written
in the awful form:

   z = datetime.datetime(*x.timetuple()[:3])

but that's hardly better, and definitely more inscrutable.

To answer Donnal's question above, however, it appears this
might be a reasonable approach:

 >>> x.timetuple() == y.timetuple()

Not sure there's a better approach readily available.
