The “aria-label” attribute must not be specified on any “time” element unless the element has a “role” value other than “caption”, “code”, “deletion”, “emphasis”, “generic”, “insertion”, “paragraph”, “presentation”, “strong”, “subscript”, or “superscript”.

The <time> element does not support the aria-label attribute when it has no explicit role or when it carries certain generic roles.

The <time> element has an implicit ARIA role of time, but this role is not listed among those that allow aria-label. According to the ARIA in HTML specification, aria-label is only permitted on elements with roles that support naming from author — and the default role of <time> (as well as roles like generic, presentation, paragraph, and others listed in the error) does not qualify.

In practice, the <time> element already conveys its meaning through its visible text content and the machine-readable datetime attribute. Screen readers use the visible text to announce the date, so aria-label is typically unnecessary.

To fix this, simply remove the aria-label attribute and ensure the visible text content is descriptive enough. If you need to provide a more accessible reading of the date, you can adjust the visible text itself or wrap the element with a <span> that has an appropriate role.

Also note the original code has a missing space before datetime — the attribute must be separated from class="Tag" by a space.

HTML Examples

❌ Invalid: aria-label on <time>

<time aria-label="Apr 2." class="Tag" datetime="2026-04-02">
  Apr 2.
</time>

✅ Fixed: Remove aria-label and use clear visible text

<time class="Tag" datetime="2026-04-02">
  April 2, 2026
</time>

If you truly need aria-label, you can assign an explicit role that supports naming, such as role="text", though this is rarely necessary:

<time role="text" aria-label="April 2nd, 2026" class="Tag" datetime="2026-04-02">
  Apr 2.
</time>
