A page can show its own title, its date, its summary and its picture, without
you typing any of them twice.

## Why you would

You have already typed the title into the title field. Typing it again into a
heading means two copies, and the day you rename the page only one of them
changes.

The same goes for the date under an article, the summary in a lead paragraph,
and the picture at the top.

## What a page can show about itself

```liquid
<h1>{{ page.title }}</h1>
<p class="lead">{{ page.excerpt }}</p>
<time datetime="{{ page.date }}">{{ page.date | date: "%e %B %Y" }}</time>
```

The fields are the same ones a list can read — see
[What a page knows about another page](/dynamic/what-a-page-knows) for all
of them. The common ones:

| Field | What it is |
| --- | --- |
| `page.title` | The page's title. |
| `page.date` | Its publication date — see [Dates](/dynamic/dates). |
| `page.excerpt` | The summary from its settings. |
| `page.url` | Its own address. |
| `page.image` | Its picture, or nothing. |

## Its picture

Guard it, because a page without one has nothing there:

```liquid
{% if page.image %}
  <img src="{{ page.image.src }}" alt="{{ page.image.alt }}">
{% endif %}
```

## About the site

The site itself has a few too, which is how a footer says your business name
without it being typed into every page:

```liquid
<footer>© {{ site.title }}</footer>
```

## Your own facts

For anything that is not one of the fields above — your phone number, your
opening hours — write it once, in the [block](/pages/blocks) that shows it on
every page, usually the header or the footer. Change it there and every page
changes with it.

## On an item's page

An item of a [collection](/dynamic/collections) — an article, a portfolio
piece — has its own values too, as `item.fields`:

```liquid
{% if item.fields.author %}
  <p class="byline">By {{ item.fields.author }}</p>
{% endif %}
```

## The rule of thumb

**If the information is already somewhere in your dashboard, show it rather
than retype it.** A page's own fields, an item's fields, or — when
you want information from *other* pages — [a list](/dynamic/why-lists-go-stale).

## You can just ask

"Put the publication date under the heading" is a request, not something you
have to write. This page is here so you know it is possible and can read what
the AI wrote.
