The time element is used to represent a specific moment in time.

The datetime attribute is used to translate dates and times into a machine-readable format.
This is important, because it helps with search engine results and helps the browser process date and time information more effectively.
The value for the datetime attribute must be either a valid year, valid month, valid time, local date, global date, or valid duration string.
Here is another example of using the time element to represent a particular date:
:::interactive_editor
<p>
The graduation will be on <time datetime="2024-06-15T15:00">June 15</time>
</p>
:::
The value for the datetime attribute is in the ISO 8601 format. ISO 8601 is an international standard to represent dates and times.
The first part of that value is the year, month and day. The capital T in the value is a separator between the date and time.
The fifteen hundred hours would be three PM in the afternoon.
Whenever you need to represent events, publication dates, or appointments, it is best to use the time element.
