O ”, that is, the total number of days X corresponding to the designated day of the year is equal to or greater than the second lunar calendar standard total number of days“ 46838 ”.
The second lunar calendar reference total number of days "46838" corresponding to the first lunar calendar reference date of January 1, 1450 is read from the lunar calendar reference total number of days register 41e, and the difference from the designated date total number of days X is "X-46838". Is required (Step A
8, A9).

In other words, in this step A9, the date on the lunar calendar indicated by the total number of days X corresponding to the designated day of the year is the day after the second lunar calendar reference date "January 1, 1450". The second lunar calendar reference date “January 1, 1450” corresponding to the total number X of designated days
"X-46838" is the number of days from "Day"
The address pointer indicating the second lunar calendar reference year 1450 on the lunar calendar table (see FIG. 4) is set in the lunar calendar table year pointer 41h, which is stored in the day register 41f in the AM 25 (step A10).

On the other hand, in step A2, "YE
S ”, that is, the total number of days X corresponding to the designated day of the year is less than the first lunar calendar standard total number of days“ 29118 ”, so it is determined that the designated day of the year exists in less than 1400 years on the lunar calendar.
The total number of days corresponding to the lunar calendar September 10, 1318, that is,
The total number of days "307" corresponding to the minimum displayable date is in ROM
It is read from the minimum value data 31b for all days of the year in 22
The difference from the total number X of designated days is obtained as "X-307" (steps A11 and A12).

In other words, in this step A12, the date on the lunar calendar indicated by the total number of days X corresponding to the designated day of the year is the day after the minimum displayable lunar calendar date "September 10, 1318". It is requested whether or not it exists. The minimum displayable lunar calendar day corresponding to this specified number of all days X is 1318 9
The number of days data "X-307" from "Month 10th" is stored in the number of days register 41f in the work RAM 25, and the lunar calendar table year pointer 41h indicates the minimum lunar year 1318 that can be displayed on the lunar calendar table (see FIG. 4). Is set (step A13).

As described above, the reference year pointer setting process of the lunar calendar table in FIG. 7 (steps A1 to A7)
Accordingly, the address pointer indicating the first year “1400” on the lunar calendar table where the total number of days X “34306” corresponding to the designated day of the year “February 1, 1994” exists is set in the lunar calendar table year pointer 41h. Then, the process proceeds to the lunar calendar date acquisition process corresponding to the designated day of the year "February 1, 1994" (step SB).

FIG. 8 is a flow chart showing the process of acquiring the lunar calendar date associated with the conversion / display process of the calendar / display of the calendar on the calendar display device. That is, first, the lunar year “1400” indicated by the current lunar table pointer 41h.
The number of days for one year corresponding to the “year” is the number of days data “1,” for each month of the year in the lunar calendar table (see FIG. 4).
Based on "0,1,0,1,0,0,1,0,1,1,0", it is calculated as "29 × 6 + 30 × 6 = 354 days" (step B1).

Then, the total number of designated days X "3430" stored in the number-of-days register 41f in step A6.
“January 1, 1400 until the lunar calendar date corresponding to 6”
From the number data "5188" after "day", the number data "35" for one year of the lunar calendar year "1400" indicated by the lunar calendar table year pointer 41h calculated in the step B1.
4 days "is subtracted as" 5188-354 = 4834 ", and the result of this subtraction is the number of days data" 4834 "after the lunar calendar year" 1401 "up to the lunar calendar date corresponding to the designated day of the year. Is rewritten and stored in the days register 41f (step B2).

Then, it is judged whether or not the number-of-days data "4834" stored in the number-of-days register 41f is "negative". In this case, since the number-of-days data "4834" is "positive", the lunar table The year pointer 41h is updated by (+1), and 1401 on the lunar calendar table is designated (step B3 → B4).

After that, the processes of steps B1 to B4 are repeatedly executed, and from the number-of-days data "4834" stored in the number-of-days register 41f, 1 of each year after the lunar calendar 1401 indicated by the lunar calendar table year pointer 41h. The number-of-days data is sequentially subtracted, and in step B4, when the lunar calendar table year pointer 41h is (+1) and 1414 on the lunar calendar table is pointed to, in steps B1 and B2, The number of days data after the lunar calendar 1414 up to the lunar calendar date corresponding to the designated day of the year stored in the hour register 41f "22
When the number data “355 days” for one year of the lunar calendar 1414 is subtracted from “8”, “228-355 = −1”
27 ”is newly stored in the number-of-days register 41f, and the subtraction result is determined to be“ negative ”in step B3.

Then, the number-of-days data "-127" stored in the number-of-days register 41f is replaced by the number-of-days data "355 days" for one year of the lunar calendar 1414 immediately before the "-127".
127 + 355 = 228 ", and the lunar calendar date corresponding to the designated day of the Christian era is obtained as the 228th day of the lunar calendar 1414 and stored in the number-of-days register 41f (steps B3 → B5).

Next, in step B5, the lunar calendar table year pointer 41h indicates the lunar calendar "from the date data" 228 "of the lunar calendar 1414 indicating the lunar calendar date corresponding to the designated day of the year stored in the day register 41f. 141
The number of days in each month in "4 years" is 14 on the lunar calendar table.
The subtraction processing is performed according to the date data of each month of 14 years. First, according to the date data "1" of January 1414 of the lunar calendar, the number data "228" indicating the lunar calendar date is "228-30 = 198". When the subtraction process is performed as "," the number data "198" from February 1414 of the lunar calendar to the lunar calendar date corresponding to the designated day of the Christian era is
It is rewritten and stored in the days register 41f (step B6).

Then, it is judged whether or not the number of days data "198" stored in the number of days register 41f is "negative". In this case, the number of days data "198" is "positive".
Therefore, the lunar calendar table month counter 41i is incremented from "1" to "2", and
February 4th is instructed (steps B7 → B8).

After that, the processes of steps B6 to B8 are repeatedly executed, and from the number-of-days data "198" stored in the number-of-days register 41f, each month after February 1414 of the lunar calendar indicated by the lunar calendar table month counter 41i. The number of days data for each is subtracted one after another.
8, the lunar calendar table month counter 41i is (+1)
Then, when August 1414 on the lunar calendar table is designated, in step B6, the number of days register 41 is then set.
The day data "21" from August 1, 1414 until the lunar calendar date corresponding to the designated day of the year stored in f
From the date data of August 1414
When "day" is subtracted, "21-29 = -8" is newly stored in the day number register 41f, and the subtraction result is determined to be "negative" in step B8.

Then, the lunar calendar 1 subtracted immediately before is added to the number-of-days data "-8" stored in the number-of-days register 41f.
The number of days data for August 414 "29 days" is "-8 + 29".
= 21 ", the lunar calendar date corresponding to the designated day of the year is obtained as the 21st day of August 1414 of the lunar calendar and stored in the number-of-days register 41f (step B7 →
B9).

As a result, the lunar calendar year "1414" indicated by the lunar calendar table year pointer 41h, the lunar calendar month "8" indicated by the lunar calendar table month counter 41i, and the day number data "21" stored in the day number register 41f.
Are set in the lunar calendar date register 41g,
"August 21, 1414" is obtained as the lunar calendar date corresponding to the designated date "Tuesday, February 1, 1994" (steps B10 to B12).

On the other hand, the designated date of the year "2nd 1994"
The day of the week data of the lunar calendar date "August 21, 1414" corresponding to "Tuesday, 1st month" is the total number of designated days X "343".
Is calculated by the day calculation formula 31e [formula (3)] stored in advance in the ROM 22 on the basis of 06 ″, that is, the designated day total number X “34306” is calculated by the formula (3).
Substituting into (34306 + 3) ÷ 7 = 4901 ... the remainder 2 is set, so the remainder “2” (Tuesday) is set as day of the week data in the lunar calendar date register 41g, and the designated year of the year “1994” The lunar calendar date “Tuesday, August 21, 1414” corresponding to “Tuesday, February 1” will be obtained.

In the year pointer setting process of the lunar calendar table in FIG. 7, steps A1 and A
It is possible to display by performing the processing from 2 → A11 to A13, and determining that the lunar calendar date corresponding to the total number X of designated days is less than the first lunar calendar reference date “January 1, 1400”. The number of days from the minimum lunar calendar date "September 10, 1318" to the lunar calendar year date corresponding to the specified total number X of days is stored in the days register 41f, and the lunar calendar table year pointer 41h indicates the lunar calendar year 1318. 8 is set, the number of days for one year subtracted from the number-of-days data in steps B1 and B2 of the lunar calendar date acquisition process in FIG. Only in the first processing that indicates "the minimum day of the lunar calendar that can be displayed is" September 10, 1318 ".
It is set as the number of days from "day" to the end of December of the same year.

That is, the lunar calendar table (see FIG. 4).
Date data from September to December, 1318 "1,0,
Based on "1,0", the total number of days "118 days" is calculated, and by subtracting "10 days" for September from this,
The number of days "108 days" for the year 1318 to be subtracted from the number of days data is obtained.

Therefore, when the address pointer indicating the lunar calendar 1318 is set in the lunar calendar table year pointer 41h, it is stored in the day register 41f only in the first days data subtraction processing in steps B1 and B2. The "108 days" is subtracted from the number of days data, and the number of days for one year is sequentially subtracted from the next year onward.

If the lunar calendar table year pointer 41h is set to the lunar calendar 1318 in step B6 of the lunar calendar year / date acquisition process in FIG. 8, the initial value of the lunar calendar table month counter 41i is "September". Therefore, only in the first subtraction process of the number of days and days from the number-of-days data stored in the number-of-days register 41f, the “1318
The number of remaining days "21st" of the current month after "10th" is subtracted.

Thus, according to the lunar calendar date acquisition process in FIG. 8, the lunar calendar date “August 2, 1414” corresponding to the designated date “February 1, 1994 (Tuesday)” in the Christian era.
When "1st (Tue)" is obtained in the lunar calendar date register 41g in the work RAM 25, the lunar calendar date "1414 8"
The first day of the month to which "21st month" belongs, that is, the day of the week data of "August 1, 1414" is the corresponding "August 1, 1414".
Based on the total number of days “34286” “= X-20”
It is calculated by the day calculation formula 31e [formula (3)] stored in advance in the ROM 22 (step S5).

That is, the above-mentioned "Lunar dated August 1, 1414"
Substituting the total number of days “34286” into the formula (3) gives (34286 + 3) ÷ 7 = 4898 ... remainder 3, so the remainder “3” (Wednesday) is 1 in the lunar calendar.
It is set in the 1-Sunday register 42a in the work RAM 25 as the day of the week data.

The lunar calendar date "August 2, 1414"
The month to which "1 day" belongs, that is, the number of days of "August 1414" is acquired as "29 days" based on the corresponding date data "0" stored in the lunar calendar table, and the last date in the work RAM 25 is acquired. It is set in the register 42b (step S6).

Thus, the designated day of the year "1994"
The lunar calendar date “Tuesday, August 21, 1414” corresponding to “February 1 (Tuesday)” is obtained in the lunar calendar date register 41g, and the day of the week data “3” of the corresponding month is obtained. (Wednesday)
And the date number "29 days" are obtained in the 1st Sunday register 42a and the last date register 32b, respectively, the process proceeds to the display process of the lunar calendar (step SC).

FIG. 9 is a flow chart showing the display process of the lunar calendar that accompanies the display process of conversion of the calendar / luenical calendar by the calendar display device. FIG. 10 is a diagram showing a display state of the lunar calendar that accompanies the conversion / display processing of the year / luennial calendar of the calendar display device.

That is, first, when the display RAM 26 is cleared, the 1-Sunday register 42 in the work RAM 25 is
Lunar calendar to be displayed, stored in “a” 1414 8
Display R that should display the corresponding date "1" as display data based on the day of the week data "3" (Wednesday) of "month"
The digit row position of the calendar display area with respect to the AM 26 is initialized to each of the display row register 42d and the display digit register 42e (steps C1 and C2).

In this case, the first week row corresponding to the Wednesday digit is set as the initial digit row position. Then, the date "1" to be displayed as the first day is initially set in the display data register 42c in the work RAM 25 (step C3).

Then, the date "1" initialized in the display data register 42c is written in the display RAM 26 in correspondence with the digit row position initialized in the display row and digit registers 42d and 42e in the step C2. It is displayed on the liquid crystal display unit 13 at this time. At this time, it is judged whether or not the display for one week is completed based on the digit position set in the display digit register 42e (step C).
4, C5).

In this case, since the digit position indicated by the display digit register 42e is on Wednesday, it is determined that the display for one week has not been completed, and the date stored in the display data register 42c is ( +1) and updated to "2" (steps C5 → C6).

Then, the digit position indicated by the display digit register 42e is updated to the Thursday position (step C).
7). Here, the date "2" to be displayed next, which is stored in the display data register 42c, is compared with the final date number "29" of "August 1414" stored in the final date register 42b. It is determined whether or not the calendar display for one month is completed (step C8).

In this case, the display data register 42c
The date to be displayed next, which is stored in, is "2", and since the last number of days of the displayed month "August 1414""29" has not been exceeded, the calendar display for one month has not ended. And the display row and column registers 42d and 42e.
The date "2" is displayed RA corresponding to the digit row position set in this case (in this case, the first week row corresponding to the digit of Thursday).
It is written in M26 and displayed on the liquid crystal display unit 13 (steps C8 → C4).

After that, the processes of steps C4 to C8 are repeatedly executed to update the day of the week digit indicated by the display digit register 42e and the display data register 4
The date to be displayed next, which is stored in 2c, is updated, and the date is "3" on the first week line corresponding to the digit position on Friday, and the date is "4" on the first week line corresponding to the digit position on Saturday. Then, the data is sequentially written in the display RAM 26 and displayed on the liquid crystal display unit 13. Here, if the digit position indicated by the display digit register 42e is Saturday, it is determined that the display for one week is completed. The row position indicated by the display row register 42d is updated to the second week row (steps C5 → C9).

As a result, the calendar of "August 1414" is written in the display RAM 26 for each date according to the position of the digit line on the calendar display area indicated by the display line and digit registers 42d and 42e, and is sequentially generated. After that, when the date “29” is displayed in the fifth week line corresponding to the digit of Wednesday in step C4, the date stored in the display data register 42c is displayed in step C6. When the date is updated to "30", the date "30" to be displayed next exceeds the final date number "29" of the current month, so that it is determined in step C8 that the calendar display for one month is completed.

As a result, the designated date of the year "199"
Lunar calendar date "1414" corresponding to "February 1st, 4th"
"August 21 (Tuesday)" is converted and displayed, and the lunar calendar of one month to which the lunar calendar date "Tuesday, 21st 1414" belongs is also displayed.
