While my data reduction only uses the monthly summaries, Brian's data in its 
raw form does indeed include the dates all the way back to 1980.  One could use 
it to figure out what the New Moon or weekend cloudiness looks like.

Bernie Sanden did exactly that quite a few years back, using Brian's actual 
calendar pages and meticulously entering the days of the week in a spreadsheet. 
 If I recall correctly, he facetiously presented that Wednesday nights or 
something were the clearest.  Of course they were the clearest within 
hundredths of a percent, but by exaggerating the scale on the plot, he came up 
with something that was worthy of a pointless USA Today chart: "Numbers Show 
That We're Observing Less!"

I think he also analyzed the "Full Moon clearing" phenomenon.
