To move your Outlook schedule to your Google Calendar, Open Outlook 2003 or 2007 and click File>Import and Export>Export to a file>Next. Choose Comma Separated Values (Windows) and click Next again. Navigate to and select your Calendar folder (it should be highlighted by default), and click Next yet again. In Outlook 2003, verify the location of the saved .csv file (change it if you want to place it elsewhere), and click Next once more. In Outlook 2007, select a location for the file, give it a name, and click OK and then Next. Click Finish, set the date range for the calendar entries to be exported, and click OK.
Now open your Google Calendar, click the small down arrow next to Add in the left pane, and choose Import Calendar. Select the Browse button, navigate to and select the .csv file you just created, and click Open. Choose the calendar you want to import it to (it will likely be selected by default), and click Import.
