Adobe Workfront calculates the Duration of a project by taking into account the Start Date of the earliest task and the Completion Date of the latest task and counts the number of days between the two dates.
The Duration of the project is calculated by the following formula:
Project Duration = Completion Date of the latest task - Start Date of the earliest task
The Duration of issues on the project does not affect the Duration of the Project.
The duration of the project counts the number of days between the two task dates based on the Schedule associated with the project or the users assigned to the tasks. For information about which schedule Workfront uses to calculate duration, see Schedules overview.
There are two types of Project Duration and the formulas by which Workfront calculates them:
Project Planned Duration = Planned Completion Date of the latest task - Planned Start Date of the earliest task / Typical hour per day
Project Actual Duration = Actual Completion Date of the latest task - Actual Start Date of the earliest task / Typical hour per day
You can locate the Project Planned and Actual Durations in the following areas of Workfront:
. In the Project Details area, in the Overview section.
For more information about the Overview sub-tab of a project, see the article Manage information in the project Overview area.
In a Project report, by including the Duration or the Actual Duration fields in the report.
