When adding to-do's in your project templates, you can add a due date to the project to-dos.
For the project template you can select whether the due date should relate to the project start or end date.
Offsets exclude weekends. So a 3-day offset that is set on a Friday will run until Tuesday
Example using the project start date
A task with a 3-day offset will set the due date of this task 3 days after the project start date.
Example using the project end date
A task with a 3-day offset will set the due date of this task 3 days before the project end date.
