This makes more sense, considering winter technically starts in Dec (in the Northern Hemisphere).
Adding something in for "early 2010" and "late 2010", at least. Probably need to do something better for "Winter 2010", where this gets specified in the infobox, since Winter 2010 can be either the start of the year or the end of it.
