Relative Time
<sl-relative-time> | SlRelativeTime
Outputs a localized time phrase relative to the current date and time.
Examples
Relative Time Basics
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>
/ Shoelace 2 release date 🎉 sl-relative-time date="2020-07-15T09:17:00-04:00"
import SlRelativeTime from '@teamshares/shoelace/dist/react/relative-time'; const App = () => <SlRelativeTime date="2020-07-15T09:17:00-04:00" />;
The date
attribute 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.
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>
div.relative-time-sync sl-relative-time sync="true" javascript: const container = document.querySelector(.relative-time-sync); const relativeTime = container.querySelector(sl-relative-time); relativeTime.date = new Date(new Date().getTime() - 60000);
import SlRelativeTime from '@teamshares/shoelace/dist/react/relative-time'; const date = new Date(new Date().getTime() - 60000); const App = () => <SlRelativeTime date={date} sync />;
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>
sl-relative-time date="2020-07-15T09:17:00-04:00" format="narrow" br sl-relative-time date="2020-07-15T09:17:00-04:00" format="short" br sl-relative-time date="2020-07-15T09:17:00-04:00" format="long"
import SlRelativeTime from '@teamshares/shoelace/dist/react/relative-time'; const App = () => ( <> <SlRelativeTime date="2020-07-15T09:17:00-04:00" format="narrow" /> <br /> <SlRelativeTime date="2020-07-15T09:17:00-04:00" format="short" /> <br /> <SlRelativeTime date="2020-07-15T09:17:00-04:00" format="long" /> </> );
