Abstract: A schedule management system includes a schedule data table which stores the schedule data including an identifier of a schedule owner, the time zone, activity and the state of the schedule. A definition data table stores the definition data for determining the relation between the registration and display of the schedule and the schedule and the state in he schedule data. A schedule data registration unit accepts a schedule reservation request, determines whether the schedule registration is permitted or not based on the schedule state of the schedule data existing in the schedule data table and the definition data, and when the schedule registration is permitted, registers the reservation schedule in the schedule data table. A schedule data approval unit accepts a request from the schedule owner for approving/disapproving the schedule and rewrites the schedule state of the corresponding schedule data in the schedule data table.
