in reply to Best and Worst Nodes of The last month / year

I don't see the problem here. "Year" has more than one meaning. One meaning is the "period from Jan 1 to Dec 31, inclusive, labelled with a non-zero integer". But it could also mean a period of 365(6) days. See for instance Merriam-Webster's definition of a year, meaning 1a.
