For example, if you want to create a calendar schedule table for February 1980, use the numeric keypad in input section 1 to enter □1□9□8□0, then press the date key, numeric keypad □2, and date key. Perform the operations in order.
Then, the input data is sent to the RAM set in the write state via the input control unit 2, data bus line DB ₁ , arithmetic circuit 6, and data bus line DB ₅ .
7 and the X register digits X ₆ to X ₁₂ and Z
Date data "1980-02" is stored in digits Z ₅ to _{Z 11} of the register. Next, when the calendar key is operated, the operation according to the flow shown in FIG. 4 is executed.

First, in executing step _S1 , according to the address signal specified by the address section 14,
The operation code OP is given from the control unit 9 to the operation decoder 10 and decoded, and as a result, the operation decoder 10 reads the RAM 7.

It is determined whether the month is small or small, and whether the year is a leap year.As a result, the last day of the month is calculated and written to digits Z ₁₂ and Z ₁₃ of the Z register. In the case of February, "29" is calculated as the last day of the month and the digit is
It will be written to Z ₁₂ and Z ₁₃ .

Next, step _S3 is executed, and the arithmetic circuit 6 calculates the day of the week on the first day of the month based on the year and month data. This day of the week is calculated by calculating the number of days from the virtual reference date to the desired date, correcting this calculated number of days, and then dividing by "7". That is, assuming that the hypothetical reference date is March 1, year 0 in the Western calendar, the number of days from this reference date to day A, month B, month C in the Western calendar is determined by the following formula.

If b≧3, then 365.25×a+30.6×(b-3)+c...(1) If b<3, then 365.25×(a-1)+30.6×(b+9)+c...(2) However , (1) and (2), when calculating, the year term (first term) is rounded down to the decimal point, and the month term (second term) is rounded off to the decimal point. Next, the days of the week are determined by correcting the number of days determined by the above formula by adding "+1", dividing this by "7", and associating the remainder "0" to "6" with Sunday to Saturday. It will be done. For February 1, 1980, a=1980, b=
2. Assuming that c=1, the number of days "723167" from the base date is calculated from the formula (2), and when +1 is added to this value, the number of days "723168" is divided by "7", the remainder "5" is obtained. The remainder represents the day of the week. That is, it is determined that February 1, 1980 is a Friday, and the result of this calculation is given to the RAM 7 via the data bus line DB ₅ , and is applied to the row address signal Ua and column address signal La given from the control section 9.
