Emacs and google calendar

[Daniel Dalton]

Hi, 

Is there away to have my Google calendar sync with my emacs calendar?
I'm not sure what emacs calendar to use, but I do currently use org-mode
to schedule todo lists. If I could sync these with google calendar as
well as creating events for specific dates and times as well as
recurring events from within emacs that would be great. Then being able
to update the emacs calendar with my gmail calendar regularly would be
great so that appointments I schedule on my Android appear in emacs.  

Is this possible? It'd be really good if emacs could also maintain a
local copy of the calendar for times when I'm offline. 

Thanks for any help, 

Dan
