We are currently in the third millennium.
A thousand years ago is a millennium ago.A millennium is a thousand years.A millenium
The first millenium lasted 100 years and so finished at the end of 100 years - that is, on 31 December 1000. The second millennium started on 1 January 1001. That is 1013 years ago (answered in 2013). Of course, this answer implies that the second millennium finished on 31 December 2000 and the third millennium started on 1 January 2001 - not 1 January 2000 as assumed by millions of arithmetically challenged people across the world. Alternatively, they just wanted to party!
