Currently I can’t find a specific WordPress plugin for Calendar Wiz.

Calendar Wiz is a paid for premium calendar service. I bit like Google Calendar on steroids, as it allows you lots and lots of customisation.

I’m not 100% sure how popular Calendar Wiz is.

It does offer Website integration plugins. But these are not WordPress plugins.

What they have are

• Upcoming events plugin
• Full Calendar plugin
• Mini Calendar plugin
• Upcoming events plugin
• Events list plugin
• Events Search plugin

They work either by custom javascript or iframes
