Commas can be a tricky aspect of academic writing for many students, particularly when it comes to dates. Errors and misunderstandings can arise from a lack of comprehension regarding the rules and exceptions that govern comma usage. To alleviate any confusion, this article aims to outline when to appropriately use a comma with dates, provide clear examples, and highlight any exceptions to the standard rule.
When to place commas with dates
Generally speaking, you should put a comma if you’re stating complete dates, except when using the day-month-year format. A comma should also be placed if the day of the week is included. A comma with dates is not placed if you only give the month and year.
Comma
Complete dates
Including the day of the week
No comma
Month and year
Day-month-year format
Different Style Guides may have diverse regulations about the use of commas, and some intricate sentences may have exemptions to the typical comma placement rules. It is important to contemplate whether a comma is necessary to guarantee that your sentence is lucid and understandable.
Commas with dates
When stating complete dates and including the day of the week when stating the date, a comma should be placed with dates.
Complete dates
A comma is typically placed with dates when a complete date is stated. This is because the comma helps to separate the different components of the date (day, month, and year) and improves clarity in the sentence.
Examples
- I was born on May 10, 1995, in New York City.
- The conference will take place on October 15, 2023, at the convention center.
- Her anniversary is on December 25, 2022, and she plans to celebrate with her family.
Including the day of the week
When the day of the week is also stated along with the date, a comma is typically used. Here are three short example sentences to showcase the use of dates with the day of the week.
Examples
- We will have a meeting on Thursday, August 24, 2023.
- The event is scheduled for Sunday, October 15.
- She has an appointment on Monday, December 25, 2023.
No commas with dates
Commas with dates are not placed if only the month and year are intended to be stated or the day-month-year format is being used.
Month and year
A comma is not placed with dates if only the month and year are stated. This is because the comma is used to separate the day from the month and year.
Examples
- I started my new job in April 2023.
- The conference will take place in July 2022.
- Her birthday is in November 2021.
Day-month-year format
When using the day-month-year format for dates, no comma is typically used to separate the day and the year. This is a common practice in many countries, including the United States. Here are three short example sentences to illustrate this.
Examples
- I will be travelling on 5 October 2023.
- The deadline for submission is 15 December 2022.
- We had a meeting on 27 January 2021.
How to write dates in formal writing
In academic writing, the dates are expressed and not as ordinals. This means that there is no “th”, “rd”, or “nd” after the number. Even though the dates are read out loud as “February fourth”, they are not written like that in academic writing. However, if the date includes the word “of”, it is acceptable to use an ordinal number. This also applies when referring to a specific day without the month. All the following sentences are correct.
Examples
✓ My son was born on April 15.
✓ My son was born on the 15th of April.
✓ My son was born on the fifteenth.
