What is Duration?

The Task Duration is the difference between the Start and End Dates. The Duration indicates the time frame that is available for the task to be completed. The Duration Type of a task identifies the relationship between the number of resources assigned to a task, the total effort, and the total Duration of the task.

Typically, we would need to write a DAX measure to determine the difference between dates. However, in the xViz Gantt chart, there is no need to write a DAX measure. The visual calculates the duration for you.
