Use of commas after dates

When a sentence includes a date (month, day, and year), is it always proper to set off the year with commas?

A coworker and I disagree about what is proper punctuation, and I can't find anything conclusive online. I want to know if it is proper to set off the year with commas in a sentence that reads like this:
The meeting I attended on December 1, 2011 was lengthy but productive.
Should there be a comma after 2011 in addition to before it?
I know that commas after years are appropriate sometimes, like so:
On September 9, 1931, my father was born.
And I know that no commas are necessary when I'm using just the month and year:
March 1977 was snowy and cold.
But it's the first example above that my coworker and I disagree about. We're in the United States.
