The HTML mark up produced by this template includes an hCalendar microformat, which makes the event details parsable by computers, either acting automatically to catalogue articles across Wikipedia, or via a browser tool operated by a person, to (for example) add the subject to a calendar or diary application. For more information about the use of microformats on Wikimedia projects, please see the microformat project.

Dates will only be included if you use {{Start date}} or {{End date}} (use the former for single dates; but do not use any of these if the date is before 1583 CE).

URLs will only be included if you use {{URL}}.

Please do not remove instances of these sub-templates.

hCalendar uses HTML classes including:

  • attendee
  • contact
  • description
  • dtend
  • dtstart
  • location
  • organiser
  • summary
  • url
  • vevent


Please do not rename or remove these classes; nor collapse nested elements which use them.
