My Webster's dictionary (made of 100% y2k compliant paper) gives millennia as the plural (admittedly, I did misspell it!), with millenniums listed as an acceptable alternative, and defines it as a period of 1000 years.
A millenium is a thousand years. There were millenia before the last two, the years from 22 AD to 1022 AD were a millenium, so were the years from 4750 to 5750 on the Jewish calendar... The point is, the 1900s end tonight and the 2000s begin. Grief, what an awkward-sounding phrase, the twenty-hundreds... the nineties also end tonight, and we start what, the naughties?
