Working with Calendars
To add a calendar to your document, select Insert > Calendar in the menu.
Calendars consist of three parts: month, days of week, and dates. The first two can be hidden. You can change the font, text color, and background color of each part individually. To do this, select one of the parts and use the text and fill tools in the Inspector.
To bring up the properties dialog, double-click on the calendar. Settings on this panel let you configure the presence and location of calendar elements.
Your regional settings dictate the calendar type and whether or not your calendar starts with Sunday or Monday. You can view them in the System Preferences.
