I would expect that those binaries would be built and deployed constantly, even if they just woke up once a day to check whether it was mid-april or whenever the financial year ended. I would also expect that they would be integrated with other reporting that happened on a daily, weekly, monthly, and quarterly basis.
Do you really have an entire application binary that is only deployed and run once a year?
