hCalendar Examples in the wild

This page is an informative section of the hCalendar specification.

The following sites have published events using hCalendar, and thus are a great place to start for anyone looking for examples "in the wild" to try parsing, indexing, organizing etc.

If events on your site are marked up with hCalendar, feel free to add it to the top of this list. Please be sure to include at least one URL of a page on your site that includes actual hCalendar markup. Examples added without the URL of a page with hCalendar markup may be removed.

Want to get started with writing an hCalendar event? Use the hCalendar creator to write up an event and publish it, or follow the hCalendar authoring tips to add hCalendar markup to your page of upcoming events or events you mention in blog posts, wikis, etc.

Don't forget that you can add one of our buttons to the page, to indicate the presence of hCalendar microformats. For example: . If you can link it back to hCalendar (or even page on your website, about your use of the microformat), so much the better!

I'd be happy if some future french Pinko-marketing meetings (CantineCamp) could require the use of hCalendar for listing some informal lunches in Paris. CantineCampParis10 is an example to include a hCalendar + hCard markup on the wiki-page. When converting to vCard, "Mendès" accent is malformed in a french outlook 2003 "address book". I've looked UTF-8 example but could not find any way to correct. Any idea ? -- xtof 01:09, 26 Mar 2007 (PDT)

- dtstart/dtend are implemented on td element Tom Armitage June 23, 2006

- whilst Tails parses the "title" attribute for dtstart/dtend on any element (does Tails still do this?), that is incorrect. The title attribute only provides semantics for the <abbr> element, while for elements in general like <span>, only the contents of the element are used. This is a simplification and see hCard parsing for details. Technorati Microformats Search only looks for the title attribute on <abbr> tags per the rules from hCard parsing which apply to hCalendar parsing as well.
