A date or time or both


The time element is used to mark a date or time within a sentence.

It provides a way to specify a computer-readable time, for calendaring or other uses, while giving the reader the same time in the vernacular.


The datetime attribute defines the time in one of these computer readable formats:
  • YYYY
  • MM-DD
  • YYYY-Www (year and week)
  • hh:mm
  • hh:mm:ss
  • hh:mm:ss.mmm (time with milliseconds)
  • YYYY-MM-DDThh:mm:ss.mmm
  • YYYY-MM-DDThh:mm:ss.mmmZ (UTC time)
  • PhhH (duration in hours)
  • PmmM (duration in minutes)
  • PssS (duration in seconds)


The year <<time *datetime=2000 2000>> was a leap-year, and
<<time *datetime=2000-02-29 February 29th, 2000>> was only the
second quadricentennial leap day ever, the first and only other one
occurring in <<time *datetime=1600-02 February of the year 1600>>.
