Fortunately, it's easy to get all your calendars out of Google Calendar in a format that many scheduling applications can understand. Exported to ICS files, you can re-import your calendars into another Google Calendar or Apps account, save them for archiving or backup, and add them to many a calendaring application — online or on your computer —, of course.
