Hi John,
Thanks for reaching out! This is something that can most certainly be done for either of our calendar offerings (The Events Calendar or Events Calendar PRO). For importing events from Facebook or other sources, you’ll want to look into our Event Aggregator add-on, which provides a variety of import options from bringing your existing content in to use with our plugins. I’d be glad to answer any specific questions you might have about Event Aggregator that aren’t answered on the linked product page! 🙂
As far as trials are concerned, we don’t offer any demo or trial versions of our products at this time–rather than rely on restrictive methods such as feature-limited trial downloads, we’ve chosen to instead provide a full 30-day refund policy for all of our plugins. Feel free to deploy the full versions of our products on your site and test the complete range of features at your disposal! Should you encounter any issues, you’ll have ready access to our premium support services, and we’ll be glad to process a refund for any reason within your 30-day trial should you decide our products aren’t right for you.
I hope that helps to get you started here! Thanks again, and let us know if there’s anything else we can assist with!
