Events by default have a start and end time, which you set when choosing the Event date and time. But you can also set a duration for a Task. This is very useful and important when it comes to scheduling your day, especially if you use Sorted3’s Auto-schedule feature.
To set a duration for a Task tap on the ‘Duration’ icon in the expanded Task or Event window. Use the time scroller to choose how many minutes or hours you want to allow for the Task. You can also tap one of the preset times below the scroller (which can be customised by going to Settings -> Duration).
