You would use the Sort into subfolder action. There you can specify a pattern. I'm not sure which date you want to use but the following should apply to whatever one you end up using.
If you drag in the date attribute you want, you can click on it and see an option to edit it's format. So, the key here is that you are going to drag in a date attribute, edit its format, drag in a path separator (to indicate another subfolder), then drag in the same date attribute again, etc.
When editing the format, for the first one, remove everything but the year. For the second one, remove everything but the month, and so on.
Give that a shot and post back here if you are still having trouble with it.
