The Calendar module doesn't recognize fields I created a content type "events", with a date field and other normal settings.

I am trying to use the Calendar module to create a calendar on my Drupal site, but I am facing an issue.
When I try to edit the basic calendar, and change its argument from date:node (node updated time), then in the list of date_fields it does not show the field that I had created above. It only shows the following fields:


Node: Last comment time
Node: Post date
Node: Updated date
User: Created date
User: Last access
User: Last login


I have tried this again and again by recreating my content type, or by disabling/enabling the Calendar module, but it does not seem to work. I am using Date 7.2.x and Calendar 7.2.x.
I installed Calendar 7.x-2.x-dev, Date 7.x-2.x-dev, and Views 7.x-3.x-dev; then I created a "Test" content type to which I added a date field ("Start date").

When I edited the Calendar view, and added a new argument for the view (view arguments are called "contextual filters," in Views 7.x-3.x-dev), I followed the following steps:


I filtered out the list of arguments to show only the ones defined from the Date module; between the two argument types, I selected "Date: Date (node)."
On the settings page that Views shows after I selected the argument type, I selected the date field I added to my content type.










If you select "Date: Date (users)," then you will see all the date fields that are associated with users, as in the following screenshot.



Still, the field I added to my content type is visible in the list of fields shown in the settings page for the view argument.

The issue you are seeing is probably caused by compatibily problems between Date, and Views. I would try using Views 7.x-3.x-dev.
