Abstract: Social calendar event sharing is described. An event associated with a personal calendar can be shared as a link to a subscription to the event. One instance of the event details can be managed by a social calendar event sharing service that receives the event details, stores the event details associated with the personal calendar of the event organizer, and generates the link. The link can be used by anyone to access the event details and add the event their own personal calendars. The event details are provided as a subscription to the event so that an update to the event can be propagated to the subscribers that have added the event to their calendars.
