Abstract: A method for managing a schedule of events for a family in an online calendar accessible by users over a communication network. The method includes: (a) assigning each user a role as parent user, child user, or other user; (b) generating a calendar grid for displaying events scheduled for the users at specified times, wherein each row or column of the calendar grid indicates the scheduled events at the specified times for a user; (c) entering new events in the calendar grid based on inputs received from client devices; (d) for at least some of said events for a child user, assigning a parent user or other user to be a person-in-charge to assume responsibility for the child user at the event; and (e) transmitting data to the client devices for displaying the calendar grid to the users.
