Is it possible to create a catalog price rule based on the range of a date?

Question

Given an attribute of type Date, I know it's possible to create a catalog price rule based on math (=, >, <) for a given date. What I'm seeing if anyone knows about, is if it's possible to create one based on compound math.

Example Attribute: Custom Date

Catalog Price rule: Custom Date <= 30 days < Custom Date

so given today is 2014-12-15 , the rule would apply all products with a Custom Date of 2014-11-15 or earlier

Answer 1

No this is not possible. It only accepts a fixed date as input. To change this would require overwriting the logic of the promotional rules models
