Comma Placement--Today's Grammar Glitch

When writing just the month and year (omitting the day of the month), it is not necessary to place a comma between the month and year.

In a recent issue of The New Yorker, the author of an article about candidate Rudy Giuliani ("The Political Scene: Mayberry Man"--August 20, 2007) forgot this rule and wrote the following sentence:

In April, 2000, Hanover accepted a role in Eve Ensler's feminist play "The Vagina Monologues."

This sentence should read as follows:

In April 2000, Hanover accepted a role in Eve Ensler's feminist play "The Vagina Monologues."

ANOTHER REMINDER: The author of this sentence did get the placement of the period INSIDE the quotation marks absolutely correct. Even though the name of the play is not a complete idea, the period still goes inside the quotation marks. Periods and commas ALWAYS go inside quotation marks.
