I already wrote in a closed post (for subscribers of the blog Yahoo!) about testing Y closed at that time! Calendar. So - good news: the calendar goes into the open beta! .
As a matter of fact, almost everything was processed from scratch. Now the calendar has a new UI, built, of course, on technology Y! UI - all through AJAX-ovy; the opportunity to subscribe to other calendars, as well as share your calendar in the form of a web page, and in the format of iCal; In addition, you can give other users Y! Calendar ability to view and edit one of your calendars (which is very convenient for organizing group planning). While not all the possibilities are shown: from the plans for the future - closer integration with mail (although it now works quite decently) and support for external applications (for the time being we’ll manage with such a vague definition).
