When a user purchases a membership on the site I'm working on, he or she is entitled to discounts on lectures which occur during an academic year as well as access to special areas of the site. Consequently, the role granted doesn't expire in X months, but rather it expires on September 1 of a particular year. If it has to be an interval, it's basically the expiration date minus now, but I don't know how or where one might add that kind of rule.
I've searched for solutions here and on drupal.org, but I'm not turning up anything, and I feel I may have overlooked something right in front of me. I'd sure appreciate any pointers in the right direction.
