In the figure, 5 is a crystal oscillator, 6 is an oscillation circuit, 7 is a frequency dividing circuit that divides the output signal of the oscillation circuit B and generates a timing pulse door of 111Z, and 8 is a timing pulse door.

This is a time counting circuit which receives as input, and is composed of a second counter 8a, a minute counter 8b, and an hour counter 8c. 9 is a day counter, 1o is a day of the week counter, and 11 is a month counter. 11: J decoder circuit, time counter 8
and converts the output signal of the day counter 9 into a segment drive signal.

16 is a calendar display switching circuit, which has month display terminals M,
It has a day of the week display terminal W, and selects and outputs the output signal of either the day counter 1o or the month counter 11 using an external operation switch 19. 14 is a month display pattern conversion circuit which converts the output signal of the month counter 11 selected by the calendar display switching circuit 16 into a segment drive signal of a month display pattern in English or a month display pattern in German. 15 is a day display pattern conversion circuit;
The output signal of the day of the week counter 10 selected by the calendar display switching circuit 13 is converted into a segment drive signal of the week display pattern in English or the week display pattern in German.

18 is a display pattern selection circuit, which has English display terminals E,
It has a German display terminal, and an external operation switch 20 selects the display pattern for the month and day of the month to be displayed in English or in German. 21 is a driver circuit for driving the digital display device 1, and 16.17 is a driver circuit for driving the digital display device 1;
9.20 switch signal waveform shaping circuit.

Next, the operation of the electronic timepiece having the configuration described in "2" will be explained.

First, the case where calendar display in English is selected will be explained. The display pattern selection circuit 181d is maintained in the designated state of the English display terminal E. Therefore, when the calendar display switching circuit 16 is in the specified state of the month display terminal M, the output signal of the month counter 11 is selected by the calendar display switching circuit 16, and the month display pattern conversion circuit 14
is converted into a segment drive pattern for month display in English and supplied to the driver circuit 21, thereby displaying the calendar display sections 4a to 4c of the digital display device 1 as shown in FIG.
As shown in b), the month is displayed in English. By operating the calendar display changeover switch 19 once in this state, one pulse is generated from the waveform shaping circuit 16 and applied to the control terminal C of the calendar display changeover circuit 16. As a result, the designated terminal changes from month display terminal M to day display N4f5.
The output signal of the day counter 10 is selected by the calendar display switching circuit 16. This signal is converted by the week display pattern conversion circuit 15 into a segment drive signal for displaying the day in a foreign language and is supplied to the driver circuit 21, thereby displaying the calendar display 741 of the digital display device 1 (see FIG. 2). The day of the week is displayed in English as shown in b).

Next time you choose to view the calendar in German,
By operating the switch 20 once from the state in which the display pattern selection circuit 18 is maintained in the designated state of the English display terminal E, one pulse is generated from the waveform shaping circuit 17 and the sub-ll1lI☆i! By applying the voltage to A'F-C, the designated terminal of the display pattern selection circuit 18 is switched from the English display terminal E to the German language display terminal. Therefore, when the calendar display switching circuit 16 is in the designated state of the month display terminal M, the output signal of the month counter 11 is selected by the calendar display switching circuit 16, and the month display pattern conversion circuit 1
