Three Dollar Quill

• Wednesday: I accomplished a little, in spite of a lack of focus.
• Thursday: I started working on calendar stuff again, and made some progress laying groundwork for sensible and less-sensible future work.
• Friday: I made some more progress, and had trouble explaining it.
• Saturday: I pared back random bits of scope, thereby making the implementation mostly easier.
• Sunday: I got the generic-time-unit stuff all working, except that I was probably adding or subtracting extra copies of a constant that happens to be zero; this would be a problem for the cases where the constant is not zero.
• Monday: I got everything seemingly working, so now I just need to work on making it clearer.

Next week, maybe I'll work on this, maybe I'll jump around arbitrarily to something else. I can't run from writing tests forever...
