Disabling Weekends for your Workspace allows you to translate Milestone and Task durations from actual days to working days.
Disabling Weekends
The Workspace Owner can Disable Weekends from inside the Localization Settings section of Workspace Control Center.
You can access Workspace Control Center via your dropdown menu.
You'll find the Disable weekends tickbox in the Localization section.
Doing so will block out weekends from your Roadmap and Overviews as well as remove those days from Milestone and Project durations.
