For example, a billing statement often, by law, needs to provide a set number of days.

I think that is the point - it's all the granularity you are working with. If you are dealing with days, then adding 30 days to Jan 31st should bring you into March. If you are dealing with months, then adding 1 month to Jan 31st should bring up into Feburary.

In my opinion, that is the 'correct' default behavior for a module where you aren't sure what the end developer will need, perhaps generating warnings if you can't do an exact mapping (Jan 31st -> Feb 31st).
