Comma Rules Part II

The first three rules can be found here.

Here are three more rules that will fend off comma happiness.

Rule 4. Use commas before or surrounding the name or title of a person directly addressed.


Will you, Aisha, do that assignment for me?
Yes, Doctor, I will.

NOTE: Capitalize a title when directly addressing someone.

Rule 5a. Use a comma to separate the day of the month from the year and after the year.


Kathleen met her husband on December 5, 2003, in Mill Valley, California.

Rule 5b. If any part of the date is omitted, leave out the comma.


They met in December 2003 in Mill Valley.

Rule 6. Use a comma to separate the city from the state and after the state in a document. If you use the two-letter capitalized form of a state in a document, you do not need a comma after the state.

NOTE: With addresses on envelopes mailed via the post office, do not use any punctuation.


I lived in San Francisco, California, for 20 years. I lived in San Francisco, CA for 20 years.

Stay tuned for more comma rules. Yes, there are more. In fact, there are 21 all together.
