Punctuation of Dates?
“Put a comma between the data and the year, between the day of the week and the date, and after the year when you give a full date. [Example:] I ordered a laptop on May 3, 2007, that arrived Friday, May 18. You don’t need commas when a date is inverted (5 July 1973) or contains only month and year, month and day, or season and year. [Example:] We installed the software after its June 2007 test.
