A decade is ten years,so for at least the soonest it would be would be 2010, definitely 2011. In true mathematical terms it should be 31 December 2010. However, the end of the second millennium was celebrated on 31 December 1999. On that basis, ten years from then would be 31 December 2009. Whichever way you look at it, it cannot be 2011.

31 is, 87 isn't.
