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.
