Use Task Workdays to identify the days when work is planned or has actually occurred for an individual task. To make workday changes across an entire project, use Project Work Schedule or Role Work Schedules under Settings.
How to Customize Workdays on a Single Task
Click a task ticket to open the ticket edit window.
Toggle the dark blue bar below each day of the activity to show whether work is planned for that day.
Dark Blue= Workday
White= Non-Workday
Click Save when you're finished.
Important: The first day of an activity can not be set as a non-workday. To change the activity’s starting day, click and drag the activity on the plan or adjust the start date in the ticket edit window.
