They'll land on Feb/29 and Feb/28, respectively. > If you subscribe to d11 == d21, what do you expect to be the result > of: Why would I 'subscribe' to that? > d11 + relativedelta(months=1) > d21 + relativedelta(months=1) > > Whatever you choose it will be seriously inconsistent from one point > of view or another. They'll land on Mar/29 and Mar/28? Where's the incosistency!?

Slapping my forehead: I used the wrong year. How about 2003?
