A global time indicating calculator has a clock member with a rotating dial for calculating global standard time and advanced time in various international time zones. Indicia printed on the face of the dial and corresponding boxes on oppositely opposed faces of the calculator can be easily referenced to determine time of day at selected locations throughout the world. The faces have recesses therein to interchangeably accommodate the clock member whereby the calculator can be modified to calculate the time of day during either standard time or advanced time periods.
