The Organizer activity displays a Month Selector to the right of the Day, Week, Month and Year View to quickly find a specific day.

Month Selector
Selection of a Day, Month or Year in the Month selector will change the current day in the Day, Week, Month and Year views. The Previous Month and Next Month buttons (1), move the current day to the previous month or next month.
The Previous Year (2) and Next Year buttons move the current day to the previous year or next year. The Revert button (4) will set the current day back to the previous selection, and the Today button (5) sets the current day to today.
In addition, you can use the arrow keys, PgUp, PgDn, Home, and End keys to move the current date.
