Provided are systems, methods, and computer-readable media useful for establishing custom names for calendar events. In various implementations, subjects for calendar events are established for different users such that each user's calendar includes an event subject that is customized for the user. For example, a user may not see his or her own name as an attendee or invitee in a calendar event subject but may see other attendees or invitees listed. For calendar events with many attendees or invitees, a custom event subject can indicate names of one or several attendees or invitees, which may be favorites or other higher priority contacts for a user, with all other attendees or invitees identified generically, such as indicated by the number of names not shown.
