How to Navigate Calendar Views in Mountain Lion
The Calendar app in OS X Mountain Lion lets you display the main Calendar window just the way you like it. If you want to master Calendar, it would behoove you to spend some time experimenting with these views and with their navigation commands and options.
You can view your calendar by the day, week, month, or year. The following figure shows a weekly view. To select a view, click the Day, Week, Month, or Year button at the top.
To move back or forward, click the arrow buttons on either side of the Today button. You see the previous or next week in week view, yesterday or tomorrow in day view, and so on.
To go to today’s date, click the Go to Today button.
To add a new calendar, click the New Calendar (+) button.
You can find all these items, most of which have shortcuts, in the Calendar View menu, as shown in the following figure. This menu offers almost total control of what you see and how you navigate.
