I got the logic for the time off rules wrong .. or rather the people who wrote this didn't bother to have the functions make sense. There's an `effective()` function .. which also includes all the holidays for previous years (how the hell are they still effective?!).

I'll just ask in the time-off room ... oh look ... no one has posted any chats in here for months. It's all just log messages. I bet everyone has it muted.

I hate working on this shit.
