Now USDA Messes With the Definition of a "Month"

Not content with defining "beef" and "veal", the USDA decides there are 13 months:

"Please be advised that 2008 13th month data has been applied to the FAS U.S. Foreign Agricultural Trade Database "

(The Foreign Ag Service has redone their statistics database here and "13th month" is a term for a catchall of corrections and late reports.
