A count display system having count display devices for counting and displaying numerals of different orders of magnitude, a prescaler having a ratio of frequency division preset in accordance with the lower orders, a first gate circuit responsive to a gate control signal for supplying input signals to the prescaler for a predetermined time interval, a second gate circuit responsive to the gate control signal for supplying the output from the prescaler to the count display device of higher orders, additional circuits responsive to the gate control signal and the output from the prescaler for applying a supply of reference pulses, to the prescaler and for applying reference pulses of the same number as the reference pulses supplied to the prescaler to the count display device of the lower orders so as to calculate the difference between the limiting value of the frequency division of the prescaler and the value actually counted by utilizing the reference pulses.
