How to schedule your project's start date, due date and actual completion date:
1 - Click on the gear icon below the star icon on a project to open the “Project Properties” panel. If you are inside a project, you can access its properties by clicking on the Settings button at the top right corner of the screen.
2 - Scroll down, you will see the section to set the dates by clicking on the "+" icon.
Start date: The date on which the project is expected to begin.
Due date: The date on which the project is expected to be finished.
Actual completion date: The date the project was actually completed (You can set this date once the project is already completed).
NOTE: If the project has Limited or Restricted Access permission setting, only project admins can set and make adjustment of dates.
