Use Task Workdays to identify what days work has actually happened or what days work is planned to happen on individual tasks.
How to customize workdays on a single task:
Click to open a task ticket's edit window.
Toggle the green lights above each day on or off to indicate if work is planned to happen on that day (Green= Workday, White= Non-workday).
Click save when done.
Note: Use Ticket Workdays to identify 'one-off' scenarios throughout the schedule. To make universal changes to workdays across a project, refer to Project Work Schedule or Role Work Schedules under settings.
