This is a test of embedding the Open Web Calendar in a static site. It seems to be able to handle an arbitrary number of ICal/ICS calendars. Anyone who wanted to add a calendar could open PR to this page adding a URL to their ics file in the iframe. Users are free to update their calendars at will. I created a quick Google Calendar for this test and put an event on April 15th, 2022.

Pros:

• Simple
• Free & open source
• Actual ICS calendar hosting is the responsibility of the people scheduling the events

Cons:

• Slow to load
• No button to copy an event to your own calendar
• Actual ICS calendar hosting is the responsibility of the people scheduling the events
• Reliant on openwebcalendar.herokuapp.com which could go away in the future (although the code is open source so another host could be found).
