Hey Luke,
Thanks so much for writing in!
Great question. The Events Calendar includes a feature that allows folks to download the ICS or Google Calendar file for any event or event view right out of the box. That’s part of the free plugin, so no need to purchase anything if that’s the only feature you’re looking for. 🙂
That said, I do want to caution that our plugins do not support “pushing” content from one site to another. We do have a service called Event Aggregator that will fetch events from other sites but, at the moment, there is nothing that will automatically push content out to other sites.
Does this help answer your question? Please let me know!
Cheers,
Geoff
