How To Write Dates In APA: A Comprehensive Guide

The American Psychological Association (APA) style is a widely used format for academic papers, especially in the social sciences. One critical aspect of adhering to APA style is correctly formatting dates. From the simplest research paper to the most complex dissertation, getting your dates right ensures clarity, professionalism, and avoids any potential confusion. This guide delves into the intricacies of writing dates in APA format, covering various scenarios and offering clear examples to help you master this essential skill.

Understanding the APA Date Format: The Foundation

The core of APA date formatting is straightforward: Month Day, Year. Note the use of the comma between the day and the year. This structure is consistent across the majority of situations, including within the body of your text, in reference lists, and in tables and figures. The month is typically written out fully, although there are some nuances we’ll cover later.

Month Spelling and Abbreviations

Generally, you should spell out the month in its entirety. However, when space is at a premium, such as within tables, figures, or in the reference list (particularly when multiple dates are present), you can use the standard three-letter abbreviations, followed by a period:

  • January – Jan.
  • February – Feb.
  • March – Mar.
  • April – Apr.
  • May – May (no abbreviation needed)
  • June – June (no abbreviation needed)
  • July – July (no abbreviation needed)
  • August – Aug.
  • September – Sept.
  • October – Oct.
  • November – Nov.
  • December – Dec.

Examples of Basic APA Date Formatting

Here are some examples to illustrate the basic format:

  • Correct: October 27, 2023
  • Correct (abbreviated): Oct. 27, 2023
  • Incorrect: 27/10/2023 or 10/27/2023 (These are not APA compliant)

Formatting Dates Within the Body of Your Text: Context Matters

How you incorporate dates into the text of your paper depends on the context. You’ll often use dates to refer to specific events, studies, or the publication of sources.

Citing Research and Studies

When referring to a study or research finding, the date usually refers to the year of publication:

  • “Smith (2022) found that…”
  • “The results, published in 2021, indicated…”

When citing a specific event within a study, use the full date:

  • “The participants completed the survey on April 15, 2023.”

Referring to Historical Events

For historical events, use the standard format:

  • “The Great Depression began in October 1929.”

Date Formatting in the Reference List: A Critical Component

The reference list is where precise date formatting becomes crucial. The date format within a reference depends on the type of source.

Journal Articles

For journal articles, the date typically includes the year and the month (sometimes even the day, if available):

  • Author, A. A., Author, B. B., & Author, C. C. (Year, Month Day). Title of article. Title of Journal, Volume(Issue), Page numbers. DOI or URL

    • Example: Jones, S. R., & Davis, L. M. (2022, December 12). The impact of social media on adolescent mental health. Journal of Adolescent Psychology, 45(6), 789-805. doi: 10.1037/jad0000876

Books

For books, the date includes the year of publication:

  • Author, A. A. (Year). Title of book. Publisher.

    • Example: Smith, J. (2021). The psychology of success. Penguin Books.

Websites and Online Resources

The date format for websites depends on the information available. It often includes the year, and sometimes the month and day of publication or last update:

Dates in Tables and Figures: Concise and Consistent

Tables and figures often require concise date formatting to maintain clarity. Use the abbreviated month format to save space.

Date Formatting Within Tables

Within tables, use the format Month Day, Year (or the abbreviated version). Ensure consistency across all dates used within the table.

Date Formatting in Figure Captions

Figure captions follow the same format as the body of the text or the reference list, depending on what the date is referring to. If the date relates to a study, use the publication year. If the figure itself has a date associated with it, use the full date.

Avoiding Common Date Formatting Errors

Several common mistakes can lead to errors in APA style.

Mixing Date Formats

Never mix date formats within a single document. Maintain consistency throughout your paper, including the body, reference list, tables, and figures.

Using Unnecessary Punctuation

Avoid unnecessary punctuation. Ensure that the only punctuation used is the comma between the day and year, and the period after the abbreviated month.

Forgetting the Comma

The comma is essential between the day and the year. Leaving it out is a significant formatting error.

Dates and Version Control: Tracking Changes

When working on academic papers, especially those involving multiple drafts and revisions, it’s helpful to include the date of the last revision. This helps you and your readers track changes. This date is typically not included in the main text or the reference list. Instead, it’s often found on the title page or in the document properties.

FAQs about APA Date Formatting

Here are some frequently asked questions to help clarify any confusion:

What should I do if the date of publication is unavailable?

If the date of publication is unavailable, use “n.d.” (for “no date”) in place of the year. For example: (Smith, n.d.).

Is it okay to use a date range for a multi-year study?

Yes, you can use a date range. For example: “The study was conducted from 2020-2022.” In the reference list, you would use the year of publication.

How do I format dates when citing multiple sources by the same author in the same year?

If you’re citing multiple works by the same author published in the same year, you must differentiate them by adding a lowercase letter after the year. For example: (Smith, 2023a) and (Smith, 2023b).

What if I need to include a time with the date?

APA style typically focuses on dates. However, if the time is critical, include it after the date using the 24-hour clock. For example: “The meeting was held on October 27, 2023, at 14:00.”

How do I format dates in a PowerPoint presentation using APA style?

In PowerPoint presentations, the date format should follow the same principles as in your paper. Use the full month, day, and year, or the abbreviated month format if space is limited.
