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.

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.

    You should not use an ordinal following the date (i.e., June 29th, 2016). Instead, you should use June 29, 2016. However, if the day precedes the month, it is appropriate to use the ordinal (i.e., the 29th day of June, 2016).

      I think you confused “i.e.” with “e.g.” Because you were giving an example of an ordinal, you should have used “e.g.” and not “i.e.”

    When asking us to post, the “Post by” should capitalize the individual’s name! If this is a blog dealing with grammar, then we should use proper grammar and punctuation!
