Abstract
A time keeping apparatus has a display mode for displaying time and a power-saving mode for reducing power consumption. The time keeping apparatus has a time display unit for displaying time, a calendar display unit for displaying a present date, a control unit for stopping, in the power-saving mode, both time display by the time display unit and calendar display by the calendar display unit, and a time information storage unit for storing information relating to an elapsed time of the power-saving mode. Upon switching back to the display mode, the calendar display displays a present date on the basis of information relating to the elapsed time stored by the time information storage unit.
