Change “No feed items found” message

How do I change the “No feed items found” message. In my use case that message doesn’t make any sense. I am using it to display calendar events in a list on the front page of my site, nobody knows it’s coming from an RSS feed, so I would like to change that message to something more appropriate such as “No events found” or something like that.

I have searched through the settings in the admin dashboard but don’t see a way to customize this message. Is there a way to change this?

Thanks,
Jamie
