By default, your timeline will be set for a three month time frame. Use its toolbar to format your timeline's color and opacity. You can also use the toolbar to select the time frame displayed on your timeline:

Select the time increments you want displayed in the dropdown menu in your toolbar. You can choose from Quarters, Months, Weeks, or Days. The Auto option will be selected by default and displays increments based on the size of your timeline.
Select a time frame. You can choose between 3M, 6M, 1Y, and Custom. The Custom option provides a calendar date selector for you to choose your own start and end dates.
Expand your timeline to expose more dates by dragging the handles at either end.

After you have configured your timeline, you can add progress bars or the annotation shape to add details about what you plan to accomplish when.
