There are several methods to create a new event:

  • long press on a day (in week or month view)
  • long press on the desired time (or on the right side for all-day events) in day view 
  • in the event details dialog (after tapping on a day) press the plus button at the bottom
  • press the plus button on top (or the floating button at the bottom in agenda view)
  • long-press the app icon to access the create-event-shortcuts (you can also drag shortcuts to the homescreen for direct access)
  • use the add button on a widget

When creating a new event, simply select the calendar at the top of the screen. 

The calendar to which an event belongs, is always given in the event details.
