h-event is a simple, open format for publishing events on the web. h-event is one of several open microformat draft standards suitable for embedding data in HTML/HTML5.

h-event is the microformats-2 update for hCalendar.

Example

Here is a simple event example:

<div class="h-event">
  <h1 class="p-name">Microformats Meetup</h1>
  <p>From 
    <time class="dt-start" datetime="2013-06-30 12:00">30<sup>th</sup> June 2013, 12:00</time>
    to <time class="dt-end" datetime="2013-06-30 18:00">18:00</time>
    at <span class="p-location">Some bar in SF</span></p>
  <p class="p-summary">Get together and discuss all things microformats-related.</p>
</div>

Get started

The class h-event is a root class name that indicates the presence of an h-event.

p-name, dt-start, dt-end, p-location, p-summary, and the other h-event property class names listed below define properties of the h-event.

See microformats-2-parsing to learn more about property class names.

Properties

Inside an element with class h-event:

• p-name - event name (or title)
• p-summary - short summary of the event
• dt-start - datetime the event starts
• dt-end - datetime the event ends
• dt-duration - duration of the event
• p-description - more detailed description of the event
• u-url - permalink for the event
• p-category - event category(ies)/tag(s)
• p-location - where the event takes place, optionally a nested h-adr or h-card
• p-geo - geophysical location of the event, optionally a nested h-geo
• p-latitude - decimal latitude
• p-longitude - decimal longitude

Experimental properties currently in use in the wild but not (yet) part of the official h-entry spec:

• p-attendee - a person attending the event, optionally a nested h-card

Status

h-event is a microformats.org draft specification. Public discussion on h-event takes place on h-event-feedback, the #microformats irc channel on irc.freenode.net, and microformats-new mailing list.

h-event is ready to use and implemented in the wild, but for backwards compatibility you should also mark h-events up as classic hCalendar events.

Property Details

(stub, to be expanded)

p-location is typically a physical address, optionally marked up with h-adr, for example:

<p class="p-adr h-adr">
  <span class="p-street-address">17 Austerstræti</span>
  <span class="p-locality">Reykjavík</span>
  <span class="p-country-name">Iceland</span>
</p>

Examples in the wild

Real world in the wild examples:

• ... add uses of h-event you see in the wild here.
• W3Conf 2013 uses h-event for the main event, and h-card for all the speakers and notable attendees. The h-cards make particularly good use of implied name, url, and photo properties.
• Tantek Çelik uses h-event on his home page
• microformats.org at 7 years presentation with h-event
• Rise of the Indie Web hCards (from Personal Democracy Forum 2012 #pdf12 #pdf2012) has microformats-2 h-event and h-card markup
• WebMaker by Mozilla has h-event and h-card on event search (e.g. search near Portland Oregon) and event pages (e.g. IndieWebCamp 2012).[1]
• IndieWebCamp has microformats-2 h-event markup with nested h-cards for the organizers and the location.
• Mozilla Events page has microformats-2 h-event markup with attendees marked up with h-card.
