It certainly does. Maybe not an ordinal decade (passing from the first decade of the century to the second), but certainly a cardinal decade in the popular understanding: the 80s ran from 1980 to 1989, the 90s ran from 1990 to 1999, the noughties ran from 2000 to 2009, the teenies (?) will run from 2010 to 2019, etc.
The real question is: Why do you want the “noughties” to be over? LOL!!
So.... you’re telling us it’s a new decade in the populist sense... *sigh*
