End of the Decade?


Lots of readers objected to my assertion that the decade is not ending tonight. One sent over this excellent discussion of when the decade ends and when it begins — and why, he argues, my conclusion is wrong (I am right when it comes to millennia and centuries, but counting “decades” is really informal).

Interesting point he concedes: If we count decades they way most readers say we should (ie, ending tonight) then this means the first decade in our calendar only had nine years: AD 1–9.
