Embed Google Calendar in Apple Wiki

Hello.

I did some googling and found out that it might be possible to embed Google Calendar in Apple Wiki.

The problem here is that by default (I think), Wikis have this built in header to prevent ClickJacking (thats what I found out by googling), so no embedding is allowed. We are using the sites internally only, so it wouldn't matter even if we get this to be disabled. Because I cannot get the Wiki Calendar to change the time formats, I would like to use Google Calendar. Does someone know how to disable the header? I did not find a final solution yet.

Sincerely,

V
