Special MM issues/tasks during the academic year

I was talking with a colleague today, and we were discussing tasks that come up during specific times of the year, especially related to the academic calendar or the fiscal year. Since they may only happen one or two times per year, it may be easy to overlook them. This is an ongoing Discussion topic where we can list those types of tasks. That way, the developers can refer back to ensure that we’re not missing any critical time-sensitive tasks in the various apps.

I couldn’t think of any cataloging/metadata ones that are tied to the academic or fiscal calendar, but my cataloging antennae are rusty. Do any come to mind for anyone?
