Dates in text include a comma only if the month and then the date precede the year. Example:

“On October 10, 1980, Donita submitted her fourth book in the series.”

When using only the month and year (or date, then month, then year), do not use a comma. Examples:

“Copyright October 1980”
“On 6 October 1924 Angelina wrote her first poem.”
