Commas in Dates

When writing a date, a comma is used to separate the day from the month, and the date from the year.

July 4, 1776, was an important day in American history.

I was born on Sunday, May 12, 1968.

But if you’re writing the date in day-month-year format, you don’t need a comma.

The project will commence on 1 June 2018.

Here’s a tip:  Commas can be tricky, but they don’t have to trip you up. Grammarly’s writing assistant can help you make sure your punctuation, spelling, and grammar are tip-top on all your favorite websites. Try Grammarly for free. 

Do use a comma if you’re including a day of the week with the date. Note the use of the comma after the date when it appears in the middle of a sentence. Commas in Dates image

When you’re giving only a month and a year, you don’t need a comma.

I haven’t seen this much snow since January 2002.
