To schedule a step, open it (Runs → click a run → Steps), open the step’s more-actions menu, and click Schedule. Pick a start and end date in the panel that appears. The menu item shows the scheduled range once it’s set. For how step schedules roll up to the run, see the Overview.
From the Runs page, switch the view toggle in the header from Table to Timeline. Here you can see all of the runs scheduled in your factory on a timeline. Runs without a schedule are shown with a No schedule marker.Clicking a run on the timeline opens a side panel where you can set its scheduled start, scheduled end, and due date. The timeline reflects your changes automatically.
