Hey there and welcome to the forums!
Good question. The Events Calendar does indeed include an RSS feed (/events/feed) that can be used to feed content from one site to another, assuming the other site is set up to accept and display RSS feeds.
Another possibly, if the other site uses The Events Calendar, is to use our iCal Importer on the other site. That will allow you to automatically import events from the first site to the other on a scheduled basis. That does require that the other site is on WordPress and uses The Events Calendar though.
Does this help answer your question? Please let me know.
Cheers!
Geoff
