Relative Time

[component-header:sl-relative-time]

Outputs a localized time phrase relative to the current date and time.

Localization is handled by the browser's Intl.RelativeTimeFormat API. No language packs are required.

<!-- Shoelace 2 release date 🎉 -->
<sl-relative-time date="2020-07-15T09:17:00-04:00"></sl-relative-time>

The date prop determines when the date/time is calculated from. It must be a string that Date.parse() can interpret or a Date object set via JavaScript.

?> When using strings, avoid ambiguous dates such as 03/04/2020 which can be interpreted as March 4 or April 3 depending on the user's browser and locale. Instead, always use a valid ISO 8601 date time string to ensure the date will be parsed properly by all clients.

!> The Intl.RelativeTimeFormat API is available in all major browsers, but it only became available to Safari in version 14. If you need to support Safari 13, you'll need to use a polyfill.

Examples

Keeping Time in Sync

Use the sync attribute to update the displayed value automatically as time passes.

<div class="relative-time-sync">
  <sl-relative-time sync></sl-relative-time>
</div>

<script>
  const container = document.querySelector('.relative-time-sync');
  const relativeTime = container.querySelector('sl-relative-time');

  relativeTime.date = new Date(new Date().getTime() - 60000);
</script>

Formatting Styles

You can change how the time is displayed using the format attribute. Note that some locales may display the same values for narrow and short formats.

<sl-relative-time date="2020-07-15T09:17:00-04:00" format="narrow"></sl-relative-time><br>
<sl-relative-time date="2020-07-15T09:17:00-04:00" format="short"></sl-relative-time><br>
<sl-relative-time date="2020-07-15T09:17:00-04:00" format="long"></sl-relative-time>
