View Google Calendar offline
In addition to offline access to Gmail while you're traveling or without a strong internet connection, you can now see your Google Calendar events when you're disconnected. Offline Calendar lets 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. This feature has been available to businesses and schools using Google Apps for about a month; we're now turning it on for everyone.
Like Gmail, the offline feature of Calendar uses Gears, an open source browser extension that adds offline functionality directly to the browser.
To enable offline Calendar access, sign in to Google Calendar and look for the "Offline Beta" link in the upper right-hand corner of your account, next to your username. We've released this early and are still ironing out some kinks, so if you encounter any issues, be sure to let us know. If you access Calendar through the Premier or Education Editions of Google Apps, your domain administrator will first have to elect to turn on new features from the Domain Settings page of the Google Apps control panel.
There are multiple ways to see your calendar when you're away from your desk — in addition to offline mode, we offer two-way sync for iPhone, Android, Windows Mobile and Blackberry devices. So wherever you go, Google Calendar can be there with you.
