PURPOSE:To display the consecutive relation of the day of the week, and enable recall of calendar information of the day after obtaining such required information, by providing a scale-of-7 signal generating circuit which corresponds to one week, calendar memory circuit to store the calendar information of the day, and other circuits. CONSTITUTION:Suppose this day is Wednesday, August 31. When it is desired to know the month and date of subsequent Wednesdays, first a calendar memory inst- ruction (j) is generated by an external SW operation, and the contents of the counter of the day, Wednesday, August 31, are stored in a calendar memory circuit 16. Next, the external switch is operated once to generate +7 signal from 7 scale signal generating circuit 21. At this time, date counter 11, month counter 12, and month end correction 15 are actuated and ''7'' is added to the counter remaining information to display September 7, so that the month and date of the next week may be found. After obtaining the desired information, when other switch is operated to generate a stored content call instruction (k), the data contents of calendar, Wednesday, August 31, are set again in counters 11 to 14, so that the watch returns to the normal state. |
