BBC NEWS Technology Google acts to organise your life: "As well as being integrated with Gmail, the calendar uses so-called natural language processing technology to simplify how events are added.
It means that people can type an entry like 'lunch on Sunday 12pm' and the software will automatically add it to the calendar.
'We enable the user to create multiple calendars, share them with other people and overlay web calendars back on the user's own calendar,'said Google Calendar product manager Carl Sjogreen.
At the moment, the calendar works best with Microsoft's Internet Explorer and Firefox. In the coming months, Google aims to make it synchronise with Outlook and mobile devices."
