Description

Description: TECHNICAL FIELD [0001] The present invention relates to a month data display device that can accurately display the hour angle of the moon and the like.

[Prior art and its problems]

Conventionally, as a device for displaying month data, a moon phase (or age) display panel for displaying a moon phase on a dial of an analog clock is provided, and the phase of the moon is displayed by rotating the moon phase display panel. Is considered. These devices display the lunar phase at that date and time, for example, by rotating the lunar display panel once at about 29.5 days of the average cycle of the phases of the moon.

In addition to the lunar movement with a cycle of about one month, the lunar movement includes the lunar movement in one day, that is, the diurnal movement. The lunar movement at this time indicates the position of the moon on the celestial sphere. There is an hour angle. The hour angle of the moon means the angle formed by the meridian and the meridian when passing through the moon. The angle of the moon at the midpoint of the meridian (midnight in the northern hemisphere) is 0, and the meridian and the lunar time The westward angle (0 ° -360 °) from 0:00 to 2
It is shown at 3 o'clock. For example, if the moon's hour angle is 6 o'clock, it is 15 ゜ 6 = 90 ゜, which means that the moon can be seen 90 ゜ from the south to the west, that is, just west.

It has been long known that the above-mentioned lunar movements and diurnal movements affect the dietary activity of animals, and the lunar new moon, the full moon and the angle of the moon are 0 o'clock, 6 o'clock,
It is empirically known that 12:00 and 18:00 are suitable for fishing and hunting.

Therefore, it is extremely convenient to be able to know the moon phase and the moon's hour angle when fishing or hunting, but there is no device that can easily know such moon hour angle data. In order to know the hour angle data and the like, it was necessary to go to a specialized facility having astronomical data to check it, and it was not possible to easily know the hour angle data of the moon.

 Next, the operation of the embodiment having the above configuration will be described.

FIG. 5 is a flowchart for explaining the overall processing contents of the embodiment.

The system normally operates in step S1 of FIG.
In the T) state, for example, a time measurement process of a time unit equal to or less than a minute unit of step S2 is executed at every 16 Hz. In this sub-minute timing process, the time is measured in units of 1/16 seconds, seconds and minutes,
When the minute reaches 60 minutes, the hour carry signal is output. Then, in the next step S3, the presence or absence of the hour carry signal is determined. By the time when the carry signal is generated, and sets "1" to the flag F ₀ (S4). Here are you set "1" to the flag F ₁ is because carried out in one-hour increments the corner operation time of the month, which will be described later.

After that, the hourly timekeeping process of step S5 is executed. In this hourly timekeeping process, as a result of the minute or less timekeeping process (S2), if the hour carry signal is generated, 1 is added to the hourly data, and if the added time exceeds 24:00, the day carry signal is further added. Output.

Thereafter, in step S6, the presence or absence of the day carry signal is determined. When the day carry signal is generated, sets "1" to the flag F ₁ (S7). Here to "1" is set to the flag F ₀ is for the purpose of performing the old operation, which will be described later on a daily basis.

Then, the day, month, day of the week, and yearly clocking process of the next step S8 is executed. In this day, month, day of the week, and year timekeeping process, if a day carry signal is generated, the day of the week is changed, and 1 is added to the data of the day. As a result of the addition, if a carry on a monthly or yearly basis occurs, the time data is further updated on a monthly or yearly basis, and the updated time data is transferred to the time register X of the RAM 9.

If the time counting process is finished as described above, the flag F ₀ proceeds to step S9, it is determined whether it is set. If F ₀ = 0, that is, if the hour carry signal has not been generated, the process proceeds to the display process of step S16, and the current time data stored in the register X is displayed on the display unit 2.

On the other hand, if F ₀ = 1, it is the calculation timing for calculating the hour angle of the moon every hour, and the month hour angle calculation process of step S10 is executed.

The month hour angle calculation process in step S10 will be described in detail with reference to the flowchart of FIG.

In step S21 of FIG. 6, first, the time stored in the register X measured by the above-described clocking process is converted into the Greenwich time based on the time difference data stored in the register B, and the Greenwich time is stored in the RAM 9 stored in the register Z _0.

Then stored in a next step S22, Greenwich sidereal calculates the variable T for obtaining the viewing ascension of the moon in the register Z ₁ of RAM 9.

Here, the variable T is a value obtained by dividing the number of days elapsed since midnight, January 1, 2000 AD (Greenwich time: GMT = UT time) by the Julian century (36525 days). Year = YE, month = MN , Day = DA, hourly unit = HO, W = (YE-1900) / 4 F = FRAC (W) A = INT (1461 × W) B = INT [(MN + 7) / 10] C = INT ( 1-F) D = INT [0.44 × (MN + 4.4)] Z = A + 31 × MN + DA + (B−1) × C−B × D + HO / 24 The variable T can be expressed by the following equation.

T = (Z-36556.5) / 36525 calculates the variable T from the equation, and stores the calculated value in the register Z ₁ of RAM 9.

Next, in Step S23, the Greenwich time at UT = 0 is determined.

Assuming that Y = Z−25012, the Greenwich time K can be expressed by the following equation.

Calculates Greenwich sidereal from K = 24 × FRAC (0.0027379 × Y) above equation, and stores the calculated value in the register Z ₂ of RAM 9.

Next, in step S24, the right ascension of the moon at UT = 0 is calculated.

 α = 32084.52539 × T +14.555441 + 0.41925 × COS (477198.868 × T + 44.963) + 0.16358 × COS (962535.762 × T + 166.633) + 0.08494 × COS (413335.350 × T + 10.740) + 0.07104 × COS ( 1934.140 × T + 324.960) + 0.07048 × COS (964469.900 × T + 41.590) + 0.04389 × COS (890534.220 × T + 145.700) Assuming the right ascension of the moon: α (m) is α (m) = Expressed as 24 × FRAC (α / 24).

Calculating a visual ascension of UT = 0 o'clock month from the above equation, and stores that value in register Z ₃ of RAM 9.

Next, the UT in Greenwich is obtained from the Greenwich sidereal time and the lunar red ascension obtained in step S25 as described above.
Calculate the hour angle of the month at 0:00.

 Moon hour angle: JK can be obtained from the following equation.

Storing the corner when the month calculated from the above equation in the register Z ₄ of RAM 9.

As described above, the hour angle of the month at UT = 0 in Greenwich on that day has been obtained. Next, the calculation of the hour angle of the next day's month is performed.

First, as in step S22 stores in the register Zn +1 to the date data of the stored time to the register Z ₁ in step S26, calculates the next day of the variable T which is + 1, the register Z ₅ of RAM9 Store.

Next, in Steps S27 and S28, as in Steps S23 and S24, respectively, the right ascension of the Greenwich time and the moon at UT = 0 at the next day are calculated, and those values are stored in the register Z ₆ of the RAM 9.
And stored in Z _7.

Then, in the next step S29, from the right star at the time of the next day of Greenwich and the moon at Greenwich,
Determined angular When the month of UT = 0, and stores that value in register Z ₈ of RAM 9.

With the above calculation, the hour angle of the month of Greenwich on the day of UT = 0 and the hour angle of the next day of the month are obtained. Next, the lunar day cycle of the month is calculated in step S30.

The lunar diurnal cycle is the time from when the hour angle of the moon becomes 0h to the next hour angle of the moon becomes 0h, and indicates the time of one cycle of the diurnal movement of the moon.

Then, the lunar circadian cycle: LNR can be expressed by the following equation.

Seeking lunar day period from the above equation and stores that value in register Z ₉ of RAM 9.

FIG. 7 is a chart showing an example of calculation of the lunar circadian cycle.

For example, the hour angle of the month at UT = 0 in Greenwich is 3.
Assuming that the hour angle of the month when UT = 0 o'clock on the next day is 3.1h, DJK = 3.1h-3.8h = -0.7h.

 Therefore, the lunar circadian cycle: LNR can be obtained as LNR = 576 / (− 0.7 + 24) = 24.7h.

Returning to FIG. 6, in the next step S31, the time (UT) at which the hour angle of the month becomes 0:00 is calculated.

 The time when the hour angle becomes 0:00 can be expressed by the following equation.

In Greenwich from the above equation, we calculated the time at which the angular becomes 0:00 when the month, and stores the value in register Z ₁₀ in RAM 9.

FIG. 8 is a chart showing an example of a calculation at the time of UT when the hour angle is 0:00.

For example, if the hour angle of the moon at UT = 0 is 3.8h,
From the lunar day cycle = 24.7 hours obtained in Fig. 7, the time when the hour angle = 0h can be calculated as (24-3.8) x (24.7 / 24) = 20.79 hours (20:47).

Referring back to FIG. 6, from the time when the hour angle of the month in Greenwich obtained by the above-described calculation becomes 0:00, the next step S32
Then, the time at which the hour angle of the month is 0 o'clock at the point being counted or at the designated point is calculated.

The time t at which the hour angle of the moon is 0:00 at an arbitrary point is obtained by the following equation.

In the above equation, the longitude and the time difference from Greenwich during the time measurement or the designated point are substituted, and the hour angle of the moon at that point is 0.
Seek time as a time and stores the time in the register Z ₁₁ in RAM 9.

For example, in Tokyo at 139.75 ° east longitude, the time t at which the hour angle of the moon is 0 o'clock is the time difference between Tokyo and Greenwich (+9 hours) and the lunar diurnal cycle (24.7 hours) obtained in FIGS. 7 and 8.
Hour), the following is from UT time (20.79 hour) where hour angle = 0 hour.

When the time at which the hour angle of the month is 0 o'clock is determined at the arbitrary point by the above operation, next, at step S33, the hour angle of the month at the current time being measured or the specified time is calculated, and the register G of the RAM 9 is set. To be stored.

FIG. 9 is a chart showing a calculation example of the hour angle of the month 11:35 in Tokyo.

From the time difference (8.62 o'clock) between the lunar day cycle obtained by the above calculation = 24.7 hours, the time when the hour angle of the moon is 0h in Tokyo = 20:12, and the current time obtained = 11:35, The hour angle difference between the months at both times can be obtained by proportional calculation.

When calculating the angle difference by proportional calculation, the angle difference = 24 x 8.62
4.724.7 = 8.38h. This angle difference is the hour angle of the moon 0h (= 2
4h), the hour angle of the moon at 11:35 = 15.6
2h can be obtained.

That is, by specifying the longitude of an arbitrary point and the time difference from Greenwich, the hour angle of the month at an arbitrary time at the point can be easily obtained by the above-described calculation.

If the angular computation time of the month has been completed in this way, then in step S11 of FIG. 5, and resets the flag F ₀ to "0". Then, in the next step S12, it is determined whether or not the flag F ₁ = 1.

When the flag F ₁ = 1, that is, when the date has changed after 24 hours have passed, the process proceeds to step S13, and the moon age calculation is executed.

FIG. 10 is a detailed flowchart of the moon age calculation in step S13.

First, in step S41, the time stored in the current time register X is converted to the Greenwich time based on the time difference from Greenwich stored in the register B.

Thereafter, in step S42, the above-described variable T is calculated from the Greenwich time.

Next, in step S43, the visual meridian of the moon is calculated from the variable T obtained in step S42 by the following equation.

Lunar eclipse of the moon = 481267.9 × T + 218.3 + 6.3 × COS (45 + 4572000 × T) + 1.3 × COS (11 + 413300 × T) Similarly, in the next step S44, the sun's sight yellow from the variable T using the following equation: Calculate the sutra.

Sun optic longitude = 36000.8 x T + 280.5 + 1.9 x COS (268 + 36000 x T) From the difference between the moon optic longitude and the solar optic longitude calculated as described above, in the next step S45 the moon Find the angle of separation. The lunar separation refers to the angle between the sun and the moon as viewed from the earth, and the change in the separation changes the lunar phase. For example, when the separation angle is 0 °, the new moon, when the separation angle is 180 °, the full moon, the separation angle is 270.
In the case of ゜, it is the month of the last quarter.

Next, in step S46, the age of the moon is calculated from the above-mentioned lunar separation and the cycle of the moon. In the present embodiment, the cycle of the lunar month is an average of 29.53 days, and the age at Greenwich time is calculated by proportional calculation from the cycle and the angle of departure of the moon calculated every day. Then, the age at that point is obtained using the time difference between the corresponding point and Greenwich. That is, the moon age at an arbitrary point can be expressed by the following equation.

FIG. 16 is a chart for explaining the relationship between the lunar phase obtained by the above-mentioned lunar age calculation, the lunar separation angle and the lunar age.

If the difference between the lunar eclipse of the moon and the luminous meridian of the sun (the lunar declination) obtained by the above-described calculation is, for example, in the range of 0 ° to 22.5 °, the age of the moon is 0.0 to 1.8 in accordance with the declination. The value becomes one of the values in the day range, and the obtained moon age data is written in the register E of the RAM 9. A moon age of 0.0 to 1.8 days corresponds to a new moon.

Similarly, if the angle of separation of the moon is in the range of, for example, 157.5 ° to 202.5 °, the age of the moon is any value in the range of 13.0 to 16.6 days according to the angle of separation at that time, and the obtained age of the moon is registered in the register. Write to E. A moon age of 13.0 to 16.6 corresponds to a full moon.

The same applies to the case where the angle of separation is in another angle range.
As shown in the figure.

Referring back to FIG. 5, when the moon age calculation is completed, step S14 is performed.
Advances to, resets the data flag F ₁ to 0.

After the end of step S14, or when the flag F = 0 in the determination of step S12, the process proceeds to step S15 to perform a fishing operation.

Fishing operation is to obtain food activity data indicating the food activity of the animal from the lunar phase and the moon angle, determine whether the current time is suitable for fishing and hunting, and determine whether the current time is appropriate for the display unit 2. This is a calculation for displaying by the four fish mark display bodies 2f.

FIG. 11 is a flowchart showing the contents of the fishing operation in step S15.

First, in step ST1, lunar phase data corresponding to the age determined by the above-mentioned lunar age calculation is obtained, and further, the lunar phase data and the current time at the point being timed obtained by the lunar angle calculation described above are obtained. The data of the number of fish marks to be displayed is obtained from the hour angle data of the moon and is stored in one of the registers Z.

Then, in the next step ST2, the above step S
The numerical value obtained by T1 is stored in the register N of the RAM 9 for storing the number of displayed fish marks. For example, if the current time is most suitable for fishing and hunting, a numerical value “4” is written to the register N, and if it is the second most suitable time, a numerical value “3” is written to the register N.

FIG. 17 shows the result of the above-mentioned phishing operation,
7 is a table showing the relationship between the number of fish marks displayed in FIG.

For example, when the moon is at 0 o'clock or 12 o'clock in a new moon or a full moon, it is the most suitable time for fishing and hunting.
The value obtained by the operation of ST1 is "4", and "4" is written to the register N in step ST2. As a result, four fish marks are displayed on the display unit 2 by the display processing of step S16 in FIG. 5 described later.

Also, when the moon is a new moon or a full moon, and the moon is at 6 o'clock or 18 o'clock, or when the moon is at 0 o'clock or 12 o'clock in the first or last quarter, it is the second most suitable for fishing and hunting. When
When the lunar phase and the lunar hour angle match the above conditions, “3” is written to the register N. Thereby, three fish marks are displayed on the display unit 2.

In addition, when the moon is a new moon or a full moon,
The time other than 18:00 is the third time suitable for fishing and hunting, and “2” is written in the register N and two fish marks are displayed on the display unit 2.

Hereinafter, similarly, as shown in FIG. 17, the number of fish marks is determined based on the lunar phase and the hour angle of the moon at that time, and whether the time is suitable for fishing and hunting is determined by the number of the fish marks. Is displayed.

Therefore, from the number of displayed fish marks, it is possible to easily know a time suitable for fishing and hunting during time measurement (or at a designated point).

Returning to FIG. 5, when the fishing calculation in step S15 is completed, the display processing in step S16 is executed. In this display process, various data obtained by the above-described timing process, lunar hour angle calculation, lunar age calculation, and fishing calculation are displayed.

The contents of the display processing in step S16 will be described in detail with reference to the flowchart of FIG.

First, in a step S51, it is determined whether or not the value of the mode register M is 0. If the time display mode is M = 0,
Transferring time data stored in the current time register X in the next step S52 to the display register A _4.

Further, stored in the display register A ₁ calculates lunar phase data to be displayed from the age data stored in the register E in the next step S53.

In the present embodiment, the moon phases are displayed in nine levels,
Determine the appropriate section of age data in any of the nine steps of the moon phases, is written in the display register A ₁ as moon phase data numerical data of specifying the corresponding lunar phase display body 2a "1-9". For example, when the age data was in the range of 0.0 to 1.8 days, in order to light the first lunar phase display body 2a ₁ representing the new moon, it writes the value "1" to the display register A _1.

In the next step S54, the writing from the corner data when stored in the register G, data specifying one of the corner display body 2c when o'clock 0-23 of the display unit 2 to display register A _2.

For example, if the angle is at 0 when the month stored in the register G, displayed numerical value "0" is written in the register A _2, printed numerical corner display body when located at the top of the "0"
2c lights up. Hereinafter, the change of the hour angle data, the display register the A ₂ are written numbers are sequentially incremented, it is gradually illuminated sequentially clockwise angular display body 2c when the rod-shaped.

The results of fishing operations which is next in the step S55 described above, to determine the lighting number of fish mark display body 2f fish mark number data stored in the register N, and writes the data to the display register A _3.

Then, in the next step S56, the display register
The display unit 2 displays the display moon phase data, hour angle data, fish mark data, and time data stored in A ₁ , A ₂ , A ₃ A ₄ .

If M is not 0 in the mode determination in step S51, the flow advances to step S57 to determine whether or not the mode register M is "1".

If the correction mode is M = 1, it is determined in next step S58 whether the value of the register P is P = 0 to 5. P = 0
If it is any one of the numbers 5 to 5, one of the digits of the month, day, day of the week, hour, minute and second is the digit to be corrected, and step S5
9 In the month of the current time register X, Sunday, hour, minute, flashing display the correction target digit transfers the second data to the display register A _4.

If P = 0 to 5 is not determined in step S58, it is next determined in step S60 whether P = 6. P
If = 6, the year digit is the target digit, and the step
Current time register X of the month in the S61, the day, to transfer the day of the week and year data to the display register A ₄ to display their data.

If it is determined in step S60 that P is not 6, the process proceeds to step S62. That is, when P = 7, 8, or 9, it is time to set the time difference, longitude, and latitude from Greenwich at the point where the user wants to know the month data, and character data indicating the type of input data according to the value of P at that time.

O) and the time difference, longitude, and latitude data of the registers B, C, and D of the RAM 9 are displayed.

Further, unless M = 1 is determined in step S57, the determining that the display mode of M = 2 sunrise / sunset time, sets "1" to the display register A ₀ the process proceeds to step S63.

Then, to calculate the moon phase display data from old data register E at the next step S64, and transfers the data to the display register A _1.

Furthermore, transfers sunrise areas with the time difference based on the next step S65 the date data and time difference data, the sunset time data read out to the display register A ₄ than ROM 11, and displays these data.

Returning to FIG. 5, when any key is operated in the halt state in step S1, the process proceeds to key processing in step S17.

This key processing will be described in detail with reference to the flowchart of FIG.

First, in a step S71, it is determined whether or not the operated key is the K1 key. If the operation is the operation of the K1 key, it is determined whether or not the value of the mode register M is "0" in a next step S72. If M = 0, K1 in the time display mode
This is when the key is operated, and “0” is set in the register P in the next step S73. Here, "0" is set in the register P.
Is set in order to start the correction target digit from the second digit of P = 0 when switching to the correction mode.

Further, in the next step S74, "1" is set in the mode register M, and the operation mode is switched from the time display mode to the correction mode.

If M = 0 in the determination in step S72, the process proceeds to step S75 to determine whether M = 1. M
If = 1, it means that the K1 key has been operated in the correction mode. In the next step 76, the above-mentioned hour angle calculation, age calculation and fishing calculation of the moon are executed. Then, in the next step S77, "0" is set in the mode register M, and the mode is switched from the correction mode to the time display mode.

Here, when the mode is switched from the correction mode to the time display mode, the hour angle, the age of the moon, the phishing calculation, and the like are performed because information such as time, time difference, longitude, and latitude may be corrected in the correction mode. This is for calculating lunar phase and lunar hour angle data based on the new information set at that time.

If it is determined in step S71 that the operation is not the operation of the K1 key, the process proceeds to step S78 to determine whether the operation is the operation of the K2 key. If it is the operation of the K2 key, in the next step S79, it is further determined whether or not the value of the mode register M is "0".
If it is 0, "2" is set in the register M in the next step S80, and the mode is switched to the sunrise / sunset time display mode.

If M is not 0 in the determination in step S79, the value of the mode register M is set to “2” in step S81.
Is determined. If M = 2, the next step S82
To set the register M to "0" and switch to the time display mode.

FIG. 14 is a diagram showing a transition of a display state when the above-mentioned K1 key and K2 key are operated.

As shown in the figure, in the mode of M = 0 or M = 1, the time display mode and the correction mode can be alternately switched by the K1 key. For example, in the time display mode, the date, the day of the week, the time, and the data of the moon phase, the moon angle, and the fish mark at that point are displayed, if any.

In the mode of M = 0 or M = 2, the time display mode and the sunrise / sunset time display mode can be alternately switched by the K2 key. For example, in the sunrise / sunset time display mode, the sunrise / sunset mark display 2b lights up,
The age of the moon (22.4 days in FIG. 14) is displayed on the dot display 2g of the display unit 2, the sunrise time (5:25 in the same manner) is displayed on the upper segment display 2h, and the sunset time is displayed on the lower segment display 2i. (Similarly, 8:35 PM) is displayed.

Referring back to FIG. 12, if it is determined in step S78 that the operation is not the operation of the K2 key, the process proceeds to step S83 to determine whether the operation is the operation of the K3 key.

If the operated key is the K3 key, step S84 is further performed.
To determine whether the value of the mode register M is "1",
If = 1, the register P is incremented in step S85.

That is, in the correction mode, the correction digit can be advanced to the next by operating the K1 key.

If it is determined in step S83 that the operation is not the operation of the K3 key, the process proceeds to step S86 to determine whether the operation is the operation of the K4 key.

If the operated key is the K4 key, it is determined in step S87 whether or not the value of the mode register M is "1". If M = 1, in the next step S88, the correction digit specified by the register P is determined. Performs data correction processing.

Further, if it is determined in step S86 that the K4 key has not been operated, it means that the K5 key or the K6 key has been operated, and the flow proceeds to step S89 to execute other key processing.

FIG. 15 is a display state diagram showing an example of time correction and input of a time difference, longitude, and latitude in the correction mode. When switching from the time display mode to the correction mode by operating the K1 key, the date, day of the week and time are displayed as shown in FIG. 15 (1). Become.

Thereafter, each time the K3 key is operated, the correction digit sequentially advances to the minute digit, the hour digit, the day digit, the month digit, and the day of the week digit. Each digit blinks, and the correction can be made with the K4 key. When the K3 key is operated again in this state, the year data blinks on the digit where the second data was displayed as shown in FIG. 15 (2), and the data of the year digit can be corrected.

If you operate the K3 key further in this state, the dot display
The character "GMT" blinks on 2g, and the segment display 2h on the right side also blinks on and off, and the time difference from GMT can be entered with the K4 key. FIG. 15 (3) shows a display state when a time difference of -4 hours between GMT and New York summer time is input.

Further, when the K3 key is operated, the character “LO” indicating the longitude is blinkingly displayed on the dot display 2g, and the segment display 2i at the lower right is also blinking, so that the longitude can be input. FIG. 15 (4) shows a display example when the longitude of New York and the longitude of 74 ° east are input.

Further, when the K3 key is operated, the character "LR" representing the latitude of the dot display 2g blinks, and the segment display 2h on the right side blinks so that the latitude can be input. Fifteenth
FIG. 5 (5) shows a display example when a latitude of 41 ° in New York is input.

The latitude and the latitude data are corrected by 1 unit every time the K4 key is operated. Therefore, when fishing or the like near New York, hour angle data of the moon at that position can be obtained accurately.

As described above, in the above embodiment, when calculating the hour angle of the moon, first calculate the hour angle data of the month in Greenwich, and further convert the hour angle data to the hour angle data of the target point based on the position information. Because it is converted, hour angle calculation,
Processing such as moon age calculation can be simplified.

Therefore, for example, it is possible to realize a month data display device that can easily calculate and display the moon's hour angle data at an arbitrary point on the earth from the time difference and longitude position information from Greenwich.

Although the above embodiment has been described for the case where the present invention is applied to an electronic wristwatch, the present invention is not limited to this, and may be incorporated in a small electronic calculator, a data bank, a scheduler, an IC card, or the like.
Of course, a dedicated machine for displaying the hour angle, the moon phase and the like may be used.

In the above embodiment, the current time data is used as the time data, and the position data is set by the K4 key. However, the time data and the position are set using a numeric keypad, a time input key, a keyboard provided with a position key, or the like. Data may be input, and the hour angle of the month may be calculated based on the input data.

Further, the calculation timing of the moon age, hour angle, etc. is not limited to the unit of one day or one hour as in the present embodiment, but may be calculated at shorter time intervals. The angle may be calculated.

Further, the display of the hour angle data is not a graphic display as in the present embodiment, but, for example, the hour and minute and the hour angle may be digitally displayed.

〔The invention's effect〕
