PlaceCal supports a number of sources for events, including ICS feeds and site-specific feeds. These include:
- Columbia Systems (via XML)
- Eventbrite (via link)
- Facebook (With caveats)
- Google Calendar (via ICS)
- ICloud (via ICal ICS)
- Outlook (via ICS)
- Ticketsolve (via XML)
- Teamup (via ICS)
In general, anything that outputs an ICS feed should be viable as source of events. Please refer to the site-specific pages in the sidebar, or your calendar system’s documentation, for specific details on how to acquire feed links.
