APA: What Date Do I Use?

APA

Website Dates - 6th edition

It is sometimes confusing to know which date (if any!) to use from a website or webpage

Check the APA Style Blog for details:

Determining Website Dates

Online Documents

Here are some guidelines:

1. Use the year only for general webpages.  Exact dates should only be used for sources that are very date specific and frequently published such as social media posts, newspaper articles, podcasts, etc.

2.  If you cannot locate a date, use (n.d.) for "no date."

3. "Last updated" or "Release date" are publication dates.  Use the year as the date.

4. Copyright date at the bottom of a page does NOT necessarily mean the page you are citing is that date.  Check the other pages on the site.  If they are all the same, it is likely a site-wide footer copyright date, not the date of the specific webpage.  Do not use a site-wide footer copyright date in your reference list.  If the page you are citing has a unique copyright date, use that date in your reference, otherwise use n.d.

5.  "Last modified" date does not mean the content of the page you are viewing is that date.  It might mean the date it was put online or the date new code was added to the page. Do not use a "last modified" date in your reference.

6.  "Last reviewed" date does not mean the content of the page was changed on that date.  If there is an original date on the page, use that.  Otherwise use (n.d.) for "no date."  If a website specifically states that the material on the page was reviewed on a specific date, then use that year.

7.  In your retrieval statement, only include a Retrieved from date when content on that page is likely to change (for example, a wiki, an updating service)
