+Set the last modification date in front matter:
+
+{{< code-toggle file=content/news/article-1.md fm=true >}}
+title = 'Article 1'
+lastmod = 2023-10-19T00:40:04-07:00
+{{< /code-toggle >}}
+
+The last modification date is a [time.Time] value. Format and localize the value with the [`time.Format`] function, or use it with any of the [time methods].
+
+```go-html-template
+{{ .Lastmod | time.Format ":date_medium" }} → Oct 19, 2023
+```
+
+In the example above we explicitly set the last modification date in front matter. With Hugo's default configuration, the `Lastmod` method returns the front matter value. This behavior is configurable, allowing you to:
+
+- Set the last modification date to the Author Date of the last Git commit for that file. See [`GitInfo`] for details.
+- Set fallback values if the last modification date is not defined in front matter.
