To provide a networked attendance managing system capable of grasping an attendance situation by using an already existing gate managing system and network managing system.

In this networked attendance managing system 1 for managing attendance based on the entrance/exist data of individuals obtained from a gate managing system 10 and a network managing system 20, the daily first entrance time of each individual is used as an attendance time, and the last exit time of the individual is used as a leaving time. When personal information from the gate managing system 10 is missed, information from the network managing system 20 is complementarily supplied so that the attendance information can be grasped.
