The HTML <time> element represents a specific period in time. It may include the datetime attribute to translate dates into machine-readable format, allowing for better search engine results or custom features such as reminders.

It may represent one of the following:

Content categories Flow content, phrasing content, palpable content.
Permitted content Phrasing content.
Tag omission None; both the starting and ending tags are mandatory.
Permitted parents Any element that accepts phrasing content.
Permitted ARIA roles Any
DOM interface HTMLTimeElement

Attributes

Like all other HTML elements, this element supports the global attributes.

datetime
This attribute indicates the time and/or date of the element and must be in one of the formats described below.

Usage notes

This element is for presenting dates and times in a machine readable format. For example, this can help a user agent offer to add an event to a user's calendar.

This element should not be used for dates prior to the introduction of the Gregorian calendar (due to complications in calculating those dates).

The datetime value (the machine-readable value of the datetime) is the value of the element’s datetime attribute, which must be in the proper format (see below). If the element does not have a datetime attribute, it must not have any element descendants, and the datetime value is the element’s child text content.
