Searching for the minicalendar

Hello,

I want to insert a minicalendar on my main page but I do not find the way to create such a minicalendar. I had a look at the moduls but don't find the modul.
Background information: I updated my calender from version 2.1 to 3.4 and now I want to insert a minicalendar.

Perhaps someone can give me informations I need.

Thanks,
Akkarin
