Insert Google Calendar in Wiki page

Insert Google Calendar in Wiki page

I was able to insert a widget for <iframe> tags and embed my public Google Calendar into a wiki page.  Here is the screenshot http://screencast.com/t/MDJkZDY0MTg

Why not actually suggest this in the title of one of the Widgets? I had to kind of guess that the iframe widget might work.  I am not a Google Apps business customer, just a regular free user of a Google Account, so I don't think I can sync my Google Calendar with Zoho Projects' calendar.
