Hi,
unfortunately the part after # (i.e. #year=2011&month=1&day=28&view=month) is a fragment that is restricted to the browser, and never sent out to Joomla. So, the call that Joomla (and Tag Meta) see is:
azforcesoftball.com/calender
If you want to set meta info on this page it's possible, but you can't change them while you navigate the calendar (it refresh its data using jQuery, and is not possible to reload meta info unless you modify the component).
Let me know if you need more details.
Best regards,
Luigi
