Following hot on the heals of Gmail going offline, I'm now seeing the offline option for Google Calendar (at least in my google apps account). I set it up on my home computer earlier but didn't have a chance to find out how far in the future/past it stores offline.

Here's the support doc for it: google.com/support/calendar/bi ...

Yes it's new :)

now official: googleenterprise.blogspot.com/ ...

yep yep, its new... here are my screenshots... now if they can get this feature quickly on regular Gmail > Calendar please =)
