So on top of organizing your Gmail inbox while you're traveling or without a strong Internet connection, you will be able to see your events in Google Calendar from wherever you are. Offline Calendar will let you view your existing schedule and events, but not edit them, so you don't have to print out calendars the night before a trip.
To enable offline in Calendar:
- Sign in to Calendar.
- In the upper right-hand corner of your account, next to your username, there will be a new 'Offline Beta' link. Click this link to start the offline synchronization process.
This offline feature uses Gears, an open source browser extension that adds offline functionality directly to the browser.
