Hey Randy–thanks for checking out The Events Calendar! I’m stoked you’re giving it a good look and I hope it’s a fit for your site. 🙂
Good question. We do have an online demo that shows a default installation of the plugin.
As far as seeing how it works on your own site with your theme, The Events Calendar itself is a free download on WordPress.org and will give you a solid idea of how the calendar will work with your site. We also offer a full refund on all our purchases within 30 days, so if you decide to give The Events Calendar PRO a try, you can do so with no risk at all.
Does this help answer your questions? Please let me know if you have any follow-up questions here and I’d be happy to help. 🙂
Cheers!
Geoff
