How do i create a calendar view that uses a date from the CCK

So i have installed the Date module, views module and calendar module.
By default, the calendar views show my node in a calendar based upon the update date.
I however have created a content type that uses a date field and i want to show the nodes on a calendar based upon the value in my date field.

When i add a contextual filter and select Date from the filter list, i only see
Date: Date (node)
Date: Date (users)

When i select Date (node) i can select some fileds like update date, creation date and so on but i can't select my custom date.
When i however select my custom field instead of Date: date, i get an error saying that the calendar views require a date argument.

I also have tried clearing the cache of the views but that does not help.

How do i create such a view?
