How to create a block view that displays content one year ago from from the post date of the current node We have a surf report running on D6. One of the features that we'd like to add is a block on the node page of a surf report content-type that shows the surf report from one year ago. 

I know how to create a filter that sets the date to one year from the current date/time, but I want to make this block display the report from one year from the post date of the current node (as opposed to current date/time). 

Any ideas on this? I've racked my brain and can't think of any solutions.

Any help is appreciated!
Can Views Data Rnage be a useful module? There is another choice is Views Date Range Filter D6. You will have investigate both solution if they work for you.
