Timed Content

Timed content shows certain content based on the current date and time.

<quiet-timed-content id="timed__overview">
  <p>It's national Cat Day! 😸</p>

  <p slot="before">This will show <em>before</em> National Cat Day (October 29)</p>
  <p slot="after">This will show <em>after</em> National Cat Day (October 29)</p>
</quiet-timed-content>

<script>
  // Obtain a reference
  const timedContent = document.getElementById('timed__overview');

  // Calculate dates for this year's National Cat Day
  const currentYear = new Date().getFullYear();
  const catDayStart = new Date(currentYear, 9, 29).setHours(0, 0, 0, 0); // October = 9
  const catDayEnd = new Date(currentYear, 9, 29).setHours(23, 59, 59, 999);

  // Set the start and end dates
  timedContent.startDate = new Date(catDayStart);
  timedContent.endDate = new Date(catDayEnd);
</script>

<style>
  #timed__overview p {
    margin-block-end: 0;
  }
</style>

Examples Jump to heading #

Providing dates Jump to heading #

The most common use case is showing content during a specific period of time. Use the start-date and end-date attributes to tell the component when to show the content.

<quiet-timed-content 
  start-date="2025-12-01T00:00:00.000Z" 
  end-date="2025-12-31T23:59:59.999Z"
>
  <p>Holiday Sale! All catnip toys are 50% off!</p>
</quiet-timed-content>

You can also pass a Date object to the startDate and endDate properties.

<quiet-timed-content>
  <p>Holiday Sale! All catnip toys are 50% off!</p>
</quiet-timed-content>

<script>
  const timedContent = document.querySelector('quiet-timed-content');

  timedContent.startDate = new Date('2025-12-01T00:00:00.000Z');
  timedContent.endDate = new Date('2025-12-31T23:59:59.999Z');
</script>

Before and after slots Jump to heading #

Use the before and after slots to show different content outside of the specified date range. The before slot shows when the current date is before the start date, and the after slot shows when the current date is after the end date.

<quiet-timed-content 
  start-date="2025-08-15" 
  end-date="2025-08-17"
>
  <div>
    <h3>Sale</h3>
    <p>25% off all premium cat food!</p>
  </div>
  
  <div slot="before">
    <h3>Sale Coming Soon</h3>
    <p>Cat food sale begins August 15th!</p>
  </div>
  
  <div slot="after">
    <h3>Sale Ended</h3>
    <p>Thanks for treating your cats during our promotion!</p>
  </div>
</quiet-timed-content>

Start date only Jump to heading #

When only the start-date is provided, content will show from that date forward. This is useful for feature launches or permanent changes that take effect on a specific date.

<quiet-timed-content start-date="2025-06-15">
  <p>New feature is now available!</p>
  
  <div slot="before">
    <p>New feature coming June 15th!</p>
  </div>
</quiet-timed-content>

End date only Jump to heading #

When only the end-date is provided, content will show up until that date. This is useful for limited-time offers or deprecation notices.

<quiet-timed-content end-date="2025-03-31">
  <p>The legacy API is available until March 31</p>
  
  <div slot="after">
    <p>The legacy API has been discontinued</p>
  </div>
</quiet-timed-content>

Enabling live updates Jump to heading #

By default, the component will render the content based on the time the page was first loaded. To update the component dynamically as time passes, add the live attribute. For performance, live updates only occur every 60 seconds.

<quiet-timed-content 
 start-date="2025-05-31T14:30:00.000Z" 
 end-date="2025-05-31T14:35:00.000Z"
 live
>
  <p>Flash sale happening now! ⚡</p>
  <p slot="before">Flash sale starts at 2:30 PM UTC</p>
  <p slot="after">Flash sale ended at 2:35 PM UTC</p>
</quiet-timed-content>
