A scheduling sign system includes a main sign, at least one entity indicator, and at least one alternative indicator. The main sign displays an array of units of time. The entity indicator, which is separate from the main sign, displays information identifying an entity, e.g., a person. The alternative indicator, which is separate from the main sign and the entity indicator, displays information identifying a location, reminder, appointment, or activity, e.g., a scheduled doctor's appointment. The entity indicator indicates (e.g., points to) either a particular time on the main sign, e.g., the time of the doctor's appointment, or a particular alternative indicator. The alternative indicator indicates (e.g., points to) a particular time on the main sign or a particular entity indicator.
