I created a snippet to generate the feed:
/**
* EVENTON CUSTOM RSS FEED
*
* Add this code to your theme’s functions.php file or a custom plugin.
*
* This snippet does the following:
* 1. Registers a new RSS feed endpoint (e.g. https://fatherheart.net/?feed=eventon).
* 2. Outputs an RSS feed that loops through EventON events and includes:
* – Start Date
* – End Date
* – Location
* – Subtitle
* – Speakers
*
* The snippet now checks for an “all day” flag (evcal_allday) so that if an event is
* all day, the dates are formatted using only the date (matching the display in the event card).
*
* Refer to https://docs.myeventon.com/documentations/event-post-meta-variables/ for a list of meta variables.
