Abstract: In an apparatus and method for sharing schedule information between mobile terminals, a sending mobile terminal transmits schedule information input by a user to a receiving mobile terminal. A schedule management server monitors a position of the sending mobile terminal according to the schedule information. If the current position of the sending mobile terminal is different from position information included in the schedule information, schedule change information is transmitted to the receiving mobile terminal, which outputs the schedule information.
