This plugin determines the created, modified, and published dates for a document using three potential data sources: frontmatter metadata, Git history, and the filesystem. See [[authoring content#Syntax]] for more information.

> [!note]
> For information on how to add, remove or configure plugins, see the [[configuration#Plugins|Configuration]] page.

This plugin accepts the following configuration options:

- `priority`: The data sources to consult for date information. Highest priority first. Possible values are `"frontmatter"`, `"git"`, and `"filesystem"`. Defaults to `"frontmatter", "git", "filesystem"]`.

> [!warning]
> If you rely on `git` for dates, make sure `defaultDateType` is set to `modified` in `quartz.config.ts`.
>
> Depending on how you [[hosting|host]] your Quartz, the `filesystem` dates of your local files may not match the final dates. In these cases, it may be better to use `git` or `frontmatter` to guarantee correct dates.
