Tips:
There are 13 different calendars. Select the one you want by using the drop-down at the top next to the date field.
Calendars can often be paired with other newsfeed categories. For example, Analyst rating calendar with analyst rating categories selected in a newsfeed.
Each calendar has its own filters. You can access this menu by clicking filters on the right-hand side.
Right-clicking on the calendar area gives you several options including exporting to CSV.
