Or if you want to be able to use it across historic times
(taking account of calendar irregularities etc) then you
can get the data from the datetime module... It just
depends how open ended your lists need to be. For
months and years you are probably ok with a simple
loop approach as Hugo suggests, but if you ever need
to go to days or weeks then datetime would be safer..
