Along with list, board, and roadmap views, Dart also has a calendar view.
You can access the calendar by clicking on the layout switcher in the top right corner of the application.
From there you can create new tasks or move your existing tasks around just by clicking and dragging. From any opened task you can simply add in date ranges to specify where they exist on the calendar.
Layout Options
From the layout switcher you can also choose a toggle on whether to show absent parents or not. This is only relevant if tasks on the calendar are subtasks of other tasks. If the tasks they are subtasks of are in different dartboards, you will be able to visualize them with the toggle on.
Finally there’s also an option to “color by”. This will allow you to color the tasks in the calendar by status or other properties that may be of interest for visualization.
