Hey Adam. Thanks for posting this. This is actually a behavior of how the calendar’s RSS feed works now; it is just a basic feed, which – as with any blog – is going to show events based on date of publication (rather than date event is occurring). We’re revisiting this for 2.1 (exploring an actual Event-based feed that displays all info, etc) but at this point it’d require some customization on your end. That being said we recently helped out a user in a similar position: https://theeventscalendar.com/support/forums/topic/how-do-you-make-a-custom-rss-feed-for-upcoming-events/. Might that point you in the right direction?
