FD tries to say “twenty-ten” rather than “two thousand ten” or “two thousand and ten” when talking about what year it is. Why “twenty-ten” sounds more cool and correct isn’t clear to FD, though the fact that FD spent a lifetime saying it was “nineteen-whatever” and, when writing about US history, always said “Eighteen-whatever,” or “Seventeen-whatever.”
So why didn’t that work for 2000 – 2009? True, one never said “Nineteen-00,” it was always “Nineteen-hundred,” which was somehow idiomatic. There doesn’t seem to be a similar “twenty-hundred” in the language, so 2000 became “two thousand” and then 2001, well that was Arthur C. Clark’s fault, FD thinks, that we all said “two thousand one.” And once that got started…
Anyway, FD tries to say “twenty-ten” but hears lots of people (including the announcer on The Daily Show?) saying “Two-Thousand Ten” and variations thereon.
