{{About||details of hCalendar used on Wikipedia|:Wikipedia:Microformats}}
'''hCalendar''' (short for '''''HTML iCalendar''''') is a [[Microformats|microformat]] standard for displaying a semantic [[HTML|(X)HTML]] representation of [[iCalendar]]-format [[calendar]] information about an event, on [[World Wide Web|web pages]], using HTML classes and [[Rel attribute|''rel'' attributes]].
It allows parsing tools (for example other websites, or browser add-ons<ref>[http://microformats.org/wiki/browsers Microformats.org: Browser Support for Microformats]</ref> like [[Firefox]]'s [[Operator (extension)|Operator extension]]) to extract the details of the event, and display them using some other website, index or search them, or to load them into a calendar or diary program, for instance. Multiple instances can be displayed as timelines.
==Example==
Consider this semi-fictional example:
<pre>
   The English Wikipedia was launched
   on 15 January 2001 with a party from 
   2-4pm at 
   Jimmy Wales' house 
   (more information).
</pre>
The HTML mark-up might be:
<pre>
<nowiki>
<p>
   The English Wikipedia was launched 
   on 15 January 2001 with a party from 
   2-4pm at 
   Jimmy Wales' house 
   (<a href="http://en.wikipedia.org/wiki/History_of_Wikipedia">more information</a>)
</p>
</nowiki>
</pre>
hCalendar mark-up may be added using <code>span</code> [[HTML element]]s and the [[HTML#Attributes|classes]] <code>vevent</code>, <code>summary</code>, <code>dtstart</code> (start date), <code>dtend</code> (end date), <code>location</code> and <code>url</code>:
<pre>
<nowiki>
<p class="vevent">
   The <span class="summary">English Wikipedia was launched</span> 
   on 15 January 2001 with a party from 
   <abbr class="dtstart" title="2001-01-15T14:00:00+06:00">2</abbr>-
   <abbr class="dtend" title="2001-01-15T16:00:00+06:00">4</abbr>pm at 
   <span class="location">Jimmy Wales' house</span> 
   (<a class="url" href="http://en.wikipedia.org/wiki/History_of_Wikipedia">more information</a>)
</p>
</nowiki>
</pre>
Note the use of the <code>abbr</code> element to contain the machine readable, [[ISO8601]], date-time format for the start and end times.
