Right on the heals of the announcement that Gmail Goes Offline with Google Gears comes the announcement that Google Calendar is getting the Offline mode treatment as well. Google’s help page mentions that users can decide which calendars are available offline. “Calendar keeps you on time, even when you’re not online. Offline Calendar allows you to access your events through your browser without requiring Internet access. It’s perfect for flaky connections or for when you’re in between meetings and have no idea where you’re supposed to be next. Note that while offline, Calendar will be read-only – it will not be possible to create, edit, or delete events.”
In a very non-Google fashion, Offline Calendar is being rolled out to Google Apps users FIRST. Typically, Google Labs swag gets rolled out to regular old Gmail users first, and then it will eventually make it’s way into the Google Apps users hands. This time around, Google Apps users get first dibs.
Offline Google Calendar will work with multiple calendars, but not on first sync. Your first sync will only grab your default calendar. No worries though, once you’re synced up, you get really basic options on your Settings page to manage which calendars you want synced to your account.
The only downside… it’s read only… at least for the time being.
