Hi there Ted,
Thanks for reaching out and for your interest in our products 🙂
Event Aggregator is the product that can help you importing events to The Events Calendar. The format in which events can be imported is iCal, the standard format for event information. The events can be automatically imported to the calendar from a feed URL, but this is not a 100% sync. While new events and changes to already imported events will be synced, events deleted from the feed will still remain in the site calendar.
Please checkout Event Aggregator product page and let me know if you still have any questions I can help you with,
Best,
Nico
