Commas in dates are used to separate the day of the month from the year, and sometimes to separate parts of a sentence when a date is included.
Always place a comma between the day and the year when writing a complete date.
When writing dates, use commas to separate the month and day from the year. If the sentence continues after the year, another comma is needed after the year.
If the date does not include the year, no comma is needed between the month and the day.
A full date includes the month, day, and year. You must always use a comma after the day and after the year if the sentence continues.
The comma after the year separates the date from the rest of the sentence.
Do not use commas when writing only the month and year or only the month and day without the year.
Commas are only needed when the month, day, and year are all written together.
When proofreading, look for dates in your writing. Ask yourself: Is there a comma after the day? If the sentence continues, is there a comma after the year?
Remember: commas make dates easier to read and keep your writing clear and correct.
