A time striking device for an electronic timepiece including a time striking signal detecting means coordinately arranged and installed in a time indicating gear train of an electronic timepiece and supplying a time striking signal prior to a striking time at every striking time, a reference zero second detecting means counting timepiece driving pulses and supplying a reference zero second signal, a coincidence circuit supplying a primary time striking direction signal by the coincidence of the outputs from these two detecting means, a frequency dividing circuit counting the timepiece driving pulses and sending out the secondary time striking direction signal at a desired time interval, a selecting circuit selectively supplying the primary time striking direction from the coincidence circuit and the secondary time striking direction signal from the frequency dividing circuit to a time striking section.
