How do I cite a source with no date in MLA style?

When an online source (e.g. web page, blog post) doesn’t list a publication date, you should instead list an access date.

Unlike a publication date, this appears at the end of your MLA Works Cited entry, after the URL, e.g. “A Complete Guide to MLA Style.” Scribbr, Accessed 28 Mar. 2021.

For offline sources with no publication date shown, don’t use an access date—just leave out the date.
