Commas and the Year and the Adjective

The Adverb Being Used as a Conjunction Reading Commas and the Year and the Adjective 1 minute Next Adverbial Objective
Are there commas around the year when, with the date, it is a direct adjective? ...the May 15, 2012, letter... ...the August 9, 1939, birth date... The year following the date is always surrounded with a pair of commas.

The reason there is confusion here is the rule that says you don't put a comma between the adjective and the noun it modifies. That rule says you don't put a single separating comma between the adjective and the noun it modifies.

This is not a single comma. This is a pair of commas, which you can put anywhere. If you take out the year, both commas go with it. Happy punctuating! Margie
