Call a specific calendar view through the URL

You can't :)

This should do it. Untested.

/fullcalendar?year=2011&month=09&day=01&mode=agendaDay

All options are here: http://arshaw.com/fullcalendar/docs/views/Available_Views/

Nice! Should work indeed, didn't knew you could do that with fullcalendar. I thought it always used the first view of an array. But you can choose one. Nice :)

I think this can go back?

For D6 too: http://drupalcode.org/project/fullcalendar.git/commit/1ebf12b

Currently, this does not work at day-level. It works at month and week level but not at day level, because the parameter needed to be 'date' and not 'day'. See http://arshaw.com/fullcalendar/docs/current_date

Here is a patch to fix this!

I don't think we should add "date" in the url. But we can fix the bug

In stead of

+  if (isset($date) && is_numeric($date) && $date > 0 && $date <= 31) {
+    $settings['date']['date'] = $date;
   }

We can do

  if (isset($day) && is_numeric($day) && $day > 0 && $day <= 31) {
    $settings['date']['date'] = $day;
   }

Thanks for the fast reply. Yes, you're right, that would keep it backwards compatible.
Here's a new patch.

This patch is incorporated into the patch in this issue #1279588: Load additional events when using ajax
Putting it back to fixed.
