Abstract of the Disclosure An electronic calculator with time counting function has an input section for inputting various data control signals. When the input section inputs given data or control signals, a given calcu- lating operation is performed in a calculating circuit in accordance with these input signals under control of a calculating control circuit. The electronic calculator comprises an oscillator for outputting a reference frequency signal, a frequency dividing circuit by which an output signal from the oscillator is frequency- divided to produce a given time counting signal, and a time counting circuit in which a time counting operation is executed by the time counting signal from the frequency divider. A holding circuit for holding a time counting signal from said frequency divider is inserted between the frequency divider and the time counting circuit. The holding circuit is provided to smoothly perform a time counting function in the time counting circuit and a calcu- lating function in the calculation circuit, these circuits being asynchronous in operation. The time counting data or calculation data processed in the time counting circuit and calculation circuit are stored in one or more memory circuit and the stored data is properly displayed by a display circuit.
