There is currently not a way to query on the Calendar Item field on the Organizational Calendar. Use the below steps to obtain a list of Calendar Items on your Organizational Calendar:
  1. At top left of Altru in the toolbar, click the Organizational Calendar
  2. On the left side of Calendar underneath Filters, un-mark all items except for Calendar items
  3. At top of calendar, click Lists
  4. Right-click on your screen and select Print
