NaNoWriMo word count calendar widget not working

You may have noticed that my calendar word count widget in the sidebar reads 0 words. No, that's not my real word count! I wrote almost two thousand words last night and about 300 this afternoon, so my actual word count is currently around 2,800 (and I'm not done for the day yet).

It appears the calendar widget is not working, but the other word count widgets work fine. If the calendar widget doesn't start working properly in the next few days, I'll switch to one of the functional ones. I'm sure you are all dying to know how I am doing!
