Eh. It's really all in how you define it... but it's all arbitrary, anyway. Most people defined '99 - 2000 as the turn of the last decade and last century... though technically it really isn't either.
But the popular definition is as valid as any, as far as I'm concerned. Unless you can point to the exact moment after the big bang that time can be said to have truly begun, there are no real points in time that can be said to the "start."
Just because somebody decided to call midnight, Jan. 1st, 0001 A.D. the start of the common era doesn't make that point in time more significant or important than a second, minute, hour, day, week, month, year, decade, or century before. It's just a moment in time to point to and say: "Here."
(How's that for nerdy and geeky?)
Anyway: Snow outside. Ick. Shoveling ahead. Double ick.
Oh well... it's exercise... and that's something I could really use after the last couple of weeks of gorging and lazing around.
