You are able to select the working days for each of your tasks. Automatic scheduling applies accordingly and takes the working day into account.
To update your tasks in bulk you can use the Table Editor or the CSV reimport.
Project Progress Percent
When calculating the progress of your projects, we use the total number of working days. The number of working days is determined by the duration of each task and the working days selected.
For example, if the working week is Mon and Fri, we will only count 4 working days for a 2 week task.
