For every fourth week, why can't you use w01,w05,w09,... ? It may take a bit
of typing if you want something done every other week, but that doesn't seem
to me very hard, and using such a description avoids the complication of the
fact that every fourth week has absolutely no meaning unless you introduce
the concept of a start date.
