One way to make calendars is with Word’s Calendar Wizard.
To use the Wizard in Word 2003 or an earlier version, go to the File menu and click on New. Under Templates in the task pane, click On My Computer. Go to the Other Documents tab and double click Calendar Wizard.
If you are using Word 2007, click the Office Button and then click New. Under Templates, click Calendars. Choose Other Calendars and then double click Calendar Wizard.
If you do not see the Calendar Wizard option in either 2003 or 2007, you will need to install it. You can do so by loading your MS Office CD, or by downloading it from the Microsoft Office templates page, here.
