Cycling posts

With WP 1.5 (latest), is there a way I can have a set number of posts (say for 1 year) cycle? So that the post for June 22, 2005, would appear on the home page again on June 22, 2006.

I guess it would take modifying the postdate year after the day rolls around, but I’m not sure how to go about this. (E.g. if the post has a timestamp of June 22, 2005, post it on June 22, then perhaps a week later, modify the year so it drops off the archive and waits until June 22, 2006 to appear again.)

Anybody have any ideas for this?
