As I write this in the eastern United States, it's already 2007 in some parts of the world. Here's a really neat Web page that shows you exactly when 2007 starts around the world. (If you explore the site, you'll find lots of other countdown features.)
If you really want to get a jump on things, and those blank 2007 diary pages are staring you down, check out Wikipedia's page devoted to the year 2007. The page contains almanac info (Astrological Year: Pisces; Chinese Year: Pig), plus a listing of major events already scheduled. Need to jot down the dates for the World Economic Forum in Davos, Switzerland? Why January 24-28, of course.
My next appointment? Dinner at a Japanese hibachi restaurant, followed by the Stooges marathon and Times Square ball-dropping on TV.
