How to Correctly Format Dates in MLA Style

Academic writing requires precision, and the Modern Language Association (MLA) style is no exception. While formatting a date might seem like a minor detail, it is a critical component of academic integrity and professional presentation. Whether creating a header for a class assignment or compiling a complex Works Cited page for a research project, understanding the specific nuances of MLA date formatting is essential.

The MLA Handbook, currently in its 9th edition, provides distinct rules for dates based on where they appear in a document. The requirements for the main body of a paper differ significantly from the requirements for the bibliographic entries at the end. This comprehensive analysis explores every aspect of date formatting in MLA style, ensuring that scholarly work remains consistent and accurate.

Essential Rules for Date Formatting in MLA Style

In MLA style, the format of a date depends primarily on its location within the document. For most students and researchers, there are three primary areas where dates are used: the identification header on the first page, the body of the essay, and the Works Cited list.

For a quick reference, the most common standard for academic papers involves the Day-Month-Year sequence. For example, instead of writing "October 12, 2023," the preferred academic format is "12 October 2023." However, as will be discussed in detail, certain exceptions and flexibility exist depending on the context.

The Standard Academic Format: Day-Month-Year

The Day-Month-Year format is preferred by MLA for its clarity and international standardization. In this format:

• The day is written in numerals.
• The month is written out in full (in the text) or abbreviated (in the bibliography).
• The year is written in numerals.
• No commas are used to separate the elements.

Example: 15 May 2024

While the American format (Month Day, Year) is common in business and casual correspondence, the Day-Month-Year sequence is the hallmark of the MLA style header and citation list.

Formatting the Date in the First Page Header

Every MLA-style paper begins with an identification header on the top left of the first page. This header provides the basic context for the submission. The date is the final line of this header and must follow a specific sequence.

The standard order for the header is:

1. Student’s Name
2. Instructor’s Name
3. Course Number and Name
4. Date

Header Date Example

Sarah Chen
Professor Jennifer Martinez
English 102: Composition and Literature
15 May 2024

In the header, the date should always be formatted as Day Month Year. It is important to note that the month should not be abbreviated in the header, even if it is a long month like September or December. Additionally, there is no separate title page in standard MLA format unless specifically requested by an instructor or if the project involves multiple authors. The text begins immediately below the title, which is centered below the date.

Writing Dates within the Main Text of the Essay

When writing the actual content of an essay, the rules for dates become slightly more flexible, yet the requirement for consistency remains absolute. Writers have a choice between two formats, but once a choice is made, it must be applied to every date throughout the entire body of the paper.

Option 1: Month Day, Year (American Style)

This format is familiar to most domestic students. If this option is chosen, a comma must be placed between the day and the year. Furthermore, if the date appears in the middle of a sentence, a comma must also follow the year.

• Correct: On August 30, 1797, Mary Shelley was born in London.
• Correct: The treaty was signed on July 4, 1776, marking a turning point in history.

Option 2: Day Month Year (International/Military Style)

This format is often preferred in higher-level academic writing because it eliminates the need for commas, creating a cleaner look in the sentence.

• Correct: On 30 August 1797 Mary Shelley was born in London.
• Correct: The declaration was finalized on 4 July 1776.

Key Restrictions for the Main Text

Regardless of the chosen format, two rules are non-negotiable in the body of an MLA paper:

1. No Abbreviations: Never abbreviate months in the main text. Write "September," not "Sept."
2. No Purely Numerical Dates: Avoid using formats like "5/15/2024" or "05-15-24." These are considered too informal for academic discourse and can lead to confusion regarding month/day order in international contexts.

Formatting Dates in the Works Cited List

The Works Cited list is where the most rigid rules apply. The goal of the bibliographic entry is to provide all necessary information for a reader to locate the source while remaining as concise as possible.

The Day-Month-Year Requirement

Unlike the body text, the Works Cited list must use the Day-Month-Year format. This provides a uniform appearance to the bibliography, allowing readers to scan dates quickly.

Month Abbreviations in Citations

In the bibliography, MLA style requires the abbreviation of all months that are longer than four letters. This is done to save space in the entry.

Months to Abbreviate:

• January: Jan.
• February: Feb.
• March: Mar.
• April: Apr.
• August: Aug.
• September: Sept.
• October: Oct.
• November: Nov.
• December: Dec.

Months NOT to Abbreviate:

• May
• June
• July

Note that all abbreviations must end with a period. If the citation ends with the date, the period for the abbreviation also serves as the final period for the entry.

Works Cited Date Example

• Print Book: Fitzgerald, F. Scott. The Great Gatsby. Scribner, 2004. (Note: Only the year is usually required for books).
• Online Article: Chen, Sarah. "The Future of AI." Tech Today, 15 Jan. 2024, www.techtoday.com/ai-future.

Choosing the Correct Publication Date

A common challenge in MLA formatting is determining which date to use when a source provides multiple options. This is particularly prevalent with digital sources and multi-edition books.

Multiple Publication Dates

If a book lists several publication dates (e.g., 1985, 2000, 2004), the rule is to use the most recent date. This indicates that the version being cited is the most updated or the specific edition the researcher has in hand.

Online vs. Print Dates

Many news organizations publish an article online first and then in a print edition several days later. When citing such a source, the writer should use the date associated with the version they actually consulted. If the online version was read on March 3rd, but the print version came out March 6th, the citation should reflect March 3rd.

Using the Most Precise Date

If a source provides both a season (e.g., Summer 2019) and a specific date (e.g., 5 June 2019), MLA guidelines suggest using the more precise date. Precision aids in the retrieval of the source, especially for digital archives where content might change frequently.

Revised and Updated Dates

For web pages that list an original publication date and a "Last Updated" or "Revised" date, the researcher should use the date of the most recent revision. This ensures the reader knows how current the information was at the time of the research.

The Role of Access Dates

In the 9th edition of the MLA Handbook, access dates (the date the researcher viewed the website) are no longer mandatory if a publication date for the content is available. However, they are highly recommended for sources that are prone to frequent changes or those that lack a publication date entirely.

When to Include an Access Date

1. No Publication Date: If a website, blog post, or wiki does not list when the content was published, the access date must be included at the end of the citation.
2. Unstable Content: For pages that change daily (like homepages or news feeds), providing an access date gives a snapshot of when the data was retrieved.

Access Date Format

The access date appears at the very end of the Works Cited entry, after the URL. It is preceded by the word "Accessed."

• Example: "Exploring the Deep Sea." Science Hub, www.sciencehub.com/deep-sea. Accessed 28 Mar. 2021.

Formatting Date Ranges

When citing a span of time or a range of dates, MLA uses an en dash (–) to connect the start and end points. Spaces should not be placed around the en dash.

Specific Date Ranges

If a researcher is citing a period of time, such as a multi-day conference or a range of years, the format is as follows:

• Years Only: 2009–15 (Note that for the second year, you only need the last two digits if they are in the same century).
• Full Dates: 12 Nov. 2021–12 Jan. 2022.

If the month is the same for both dates in the range, do not repeat the month.

• Example: 15–20 May 2024.

Special Cases and Edge Dates

Academic research often involves sources that do not fit the standard "Author-Title-Date" mold. MLA has developed specific protocols for these scenarios.

No Date Available

For offline sources with no publication date, the date element is simply omitted. For online sources, as mentioned, the access date serves as a substitute. If a copyright date is available on the copyright page of a book but not on the title page, use the copyright year.

Performance and Live Events

When citing a live performance (such as a play, concert, or lecture), the date should be the specific day the researcher attended the event. Even if a play runs for a month, the citation must reflect the "version" of the performance witnessed.

• Example: Hamlet. Directed by Robert Icke, Almeida Theatre, London, 7 July 2018.

Social Media and Comments

For social media posts (Tweets, Instagram posts) or comments on articles, the timestamp can sometimes be important. While not always necessary, if multiple posts by the same author occur on the same day, adding the time of the post can help distinguish them. However, for most general citations, the date alone is sufficient.

Historical Dates (B.C.E. and C.E.)

In historical research, it is often necessary to specify the era. MLA uses B.C.E. (Before Common Era) and C.E. (Common Era). These labels should be placed after the year.

• Example: 50 B.C.E.

The Importance of Numerical Consistency

One of the most frequent errors observed in student papers is the inconsistent use of numerals. In MLA style, days and years are always written in numerals. Do not write "the ninth of July" or "July ninth."

• Incorrect: July 9th, 2024
• Incorrect: July ninth, 2024
• Correct: 9 July 2024
• Correct: July 9, 2024 (if consistent with body text)

Numerical suffixes like "st," "nd," "rd," and "th" are generally avoided in MLA citations and headers.

Why Consistency Matters in MLA Formatting

As an experienced academic editor, I have reviewed thousands of manuscripts where the formatting of dates was the primary detractor from the author's credibility. Consistency in date formatting is not merely about following a set of arbitrary rules; it is about signal-sending.

When a researcher uses "15 Jan. 2024" in one entry and "February 2nd, 2024" in the next, it signals to the reader (and the instructor) a lack of attention to detail. In academia, attention to detail is synonymous with the rigor of the research itself. If an author cannot be bothered to format a date correctly, the reader may wonder if they have also been careless with their data collection or their analysis of secondary sources.

Furthermore, the Day-Month-Year format used in Works Cited entries is designed to facilitate international scholarship. By placing the day first, the format avoids the confusion that often arises between the US system (MM/DD/YYYY) and the European/International system (DD/MM/YYYY).

Summary of MLA Date Formatting Rules

To ensure a paper is fully compliant with MLA 9th Edition standards, keep the following summary in mind:

*Months with 4 letters or fewer (May, June, July) are never abbreviated.

By adhering to these standards, writers can ensure their work meets the expectations of academic publishers and instructors alike. The date is a small element of the paper, but its correct execution is a hallmark of professional scholarship.

Frequently Asked Questions

Should I use a comma between the month and the year if no day is provided?

No. In MLA style, if you only provide the month and the year, do not use a comma.

• Example: The study was completed in October 2023.

How do I cite a source that has a season instead of a month?

If a journal or publication uses a season (e.g., Spring, Summer, Fall, Winter), treat the season like a month in your citation. Do not capitalize the season unless it is the first word of the citation or a title.

• Example: Journal of Modern History, vol. 45, no. 2, spring 2022, pp. 12-30.

What do I do if a web page has no date at all?

As per MLA guidelines, if no publication or modification date is visible on a web page, you should omit the date from the publication slot and instead provide an access date at the end of your entry. Use the format: Accessed [Day] [Abbreviated Month] [Year].

Is the date format different for different types of sources, like movies or podcasts?

The general principle of Day-Month-Year remains the same for the Works Cited list across all media types. For a movie, you would list the release year. For a podcast episode, you would list the specific day, abbreviated month, and year of the broadcast.

Can I use the "slash" format (e.g., 01/02/2024) in my paper?

No. Purely numerical date formats using slashes, hyphens, or periods are not acceptable in MLA style. Always write out the month name (or its abbreviation in the bibliography).

If I am citing an older book that has been republished, which date do I use?

If you are using a modern edition of a classic text (e.g., a 2004 edition of The Great Gatsby), you should cite the 2004 date as that is the version you are reading. However, if the original publication date is relevant to your argument, you can include it immediately after the title, followed by the current publication information.

• Example: Fitzgerald, F. Scott. The Great Gatsby. 1925. Scribner, 2004.
