Abstract: An online shared calendar application which facilitates communication, coordination and scheduling for users to plan get-togethers and share event information with others. Users have their own personal calendars and can upload and/or manually enter their contacts' information, create and share events, and invite or inform individuals from their contacts to their events. Inviting/sharing events automatically e-mails these contacts and updates their calendars with the event. Contacts who were invited/informed respond from their calendars. These responses send immediate and automated e-mails to the inviter and update the inviter's calendar. Thus, this is an online, shared calendar application that facilitates the sharing and coordination of events among users' contacts.
