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 Wikipedia, please see the microformat project.
