HTML <del> datetime Attribute

The datetime attribute on a <del> tag attaches a deletion datetime.

This value is not visible, but it is machine-readable.

Example

#

A <del> element with a datetime attribute.
The datetime value signifies when the deletion occurred.

Your order has been canceled cancelled. 

<p>
  Your order has been 
  <del datetime="2020-11-25T09:10:43">canceled</del> 
  cancelled.
</p>

Using datetime

The datetime attribute attaches a date (required) and time (optional) value to a del element.

Its value is not visible to the user; it only adds a semantic timestamp to the element.

The datetime values are readable by screen readers, search engines, JavaScript code, and others.

Syntax

<del datetime="YYYY-MM-DDThh:mm:ssTZD" >

Values
