Hi Michael,
Thanks for writing in!
There is indeed an iCal file included in The Events Calendar that can be found at: [your-site]/events/ical
That said, it is a file of data rather than a feed. So, in other words, a visitor can download the file and import it into the calendar of their choice, but it will not automatically sync when new events are added or edited.
On the other hand, The Events Calendar also include an RSS feed that can be used to push updates to calendars that support RSS. That can be found at: [your-site]/events/feed
Does this help answer your question? Please let me know. 🙂
Cheers!
Geoff
