The year and the state in the examples below are essential information; hence I do not believe that they should be followed by commas despite the guidance of many style guides. I believe the two examples below are okay with no comma after "California" and no comma after "2015". (1) The Sacramento, California teen was arrested on a charge of petit larceny. (2) The February 15, 2015 meeting has been canceled. (3) November 30, 1966 is my date of birth. (I say we would leave out the comma after "1966" as shown above.) Okay to the three examples above exactly as punctuated?
