It's called the 'alarm clock' on the phone, for the weekly stuff

You know what needs doing. You just need a gentle nudge to do it.

The other stuff that's months or weeks apart gets an icon with a descriptive and dated label on the desktop. As stuff gets done, you either delete it or reschedule it and move it back down to the bottom of the list. As stuff gets done and removed from the top of the list, the icons move upwards. It's very simple, and it's very effective.
