The Code

 find . -name "2013-*" -type d | xargs rm -rf

Explanation

We use the find command in the current directory(.) to search for a name starting with 2013- followed by anything, which is of type d for directory.

We then pipe (|) the found directories over to the xargs command which runs the remove command (rm) with the options of recursive (r) and forced (f) for no confirmation prompts.
