of 2004? If so, I'd be happy to say
date(d.month() + 2*months, d.day)
That, too, calls out the fact that adding months to dates has a dubious meaning.
That makes the result of the expression quite explicit. I can't see any problems with that approach. I'd expect an exception if the resulting month doesn't have the requested day. OTOH, if date's ctor were to take an extra argument, or if there was a date factory function supplying the different behavior, you could specify that you want clipping to the last day of the designated month:
date(d.month() + 2 * months, d.day(), clip_to_eom) make_date_clipped_to_end_of_month(d.month() + 2 * months, d.day())
