Abstract: A calendar-event recommendation system that generates and displays event recommendations tailored to a user. The system may recommend events based on a user's current location. The system may recommend events based on a user's social network, such as if the user's friends attend an event, or an event organized by or affiliated with a person, place, or organization the user has interest in. The system may recommend events based on receiving an invitation from others, or if the user's contacts are in the event's guest list. The system may recommend events based on the user's past behavior, such as attending similar events. The system may recommend events based on a user's subscription to categories of certain types of events. After recommending an event, the system may automatically add the event to the user's calendar, add the user's name to a guest list, and share the event with the user's contacts.
