This calendar widget integrates with Facebook. This means you can have all your events automatically linked on your website and your Facebook page. It has a step-by-step tutorial on how to create a Facebook app, which allows you to automatically import your church’s Facebook page events into your website calendar. The one downside is that currently you can only import events from a Facebook page. Read our review here!
The Custom Facebook Feed plugin by Smash Balloon is a great free Facebook plugin. You have to create a Facebook app, but after you do this, you can insert anything you want from Facebook (like buttons, Facebook feeds, etc.) anywhere on your website because it uses short codes. You can add it to your home page or footer using text widgets and add it to your pages too!
They also offer Custom Facebook Feed Pro as a premium plugin. For $39, you can add a ton more features to your Facebook feed on your website! It includes highlighting certain posts or events, adding date filters, and having multiple Facebook pages feed into your website. Click here for a demo!
