There seems to be a disagreement amongst people on how to pronounce the new year that just arrived.
Up until 1999 we called it Nineteen Ninety Nine, not One Thousand, Nine Hundred and Ninety Nine.
When the year 2000 came, calling it The Year Two Thousand sounded cool and futuristic and Twenty Zero, Zero didn't sound right.
After 2000, the "Two thousand" just stuck. Now that we're entering the "teens", pronouncing the year is going to get more complex.
Two Thousand and Ten: 4 words and 5 syllables
Twenty Ten: 2 words, 3 syllables
I think people will adopt the shorter version. What are you calling it?
