You can also use the "GoTo" button:

GoTo brings up a calendar date chooser. In month view, the date chooser is very simple - it gives you a list of other months to move to.
In week view and day view, you will see black arrows on both sides of the word "Today". Use the black arrows '>' to change the month, and the double black arrows '>>' to change the year.

Then click on a particular day to navigate to that week or month.
Clicking on "Today" will bring your calendar back to today's date.
Remember, click on "This Month", "This Week", or "This Day" in the blue command bar to instantly come back to today's date.
