Try this:

Code:
awk '/Wed Nov 9/ { print ; getline; print; while (getline && $0 != "") print ; print }' inputfile > outputfile

This fairly lazy solution assumes that there is always a blank line after the paragraph that follows the date required.

Strange, it seems to work fine for me:

Code:
$ cat inputfile
Wed Nov 9

11111111111111
22222222222222
33333333333333

$ awk '/Wed Nov 9/ { print ; getline; print; while (getline && $0 != "") print ; print }' inputfile
