Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an electronic timepiece capable of displaying the lunar phase or the age of the moon and the time angle data of the moon.

[Prior art and its problems]

Conventionally, there is known a kimono which is provided with a moon phase (or moon age) display panel for displaying the moon phase on the dial of an analog clock, and the moon phase is displayed by rotating the moon phase display panel. . This analog clock having a moon phase display function is used for checking when fish can be caught well (when the moon is full or new moon is good) and fortune-telling.

In the above analog clock, for example, the moon phase display panel is rotated once every approximately 29.5 days, which is the average period of the lunar sloppy movement, and the moon phase at that date and time is displayed.

In the analog type moon phase display described above, not only the gear mechanism inside the timepiece becomes complicated, but also the rotation cycle is fixed due to its structure, so the cycle of the actual lunar movement (about 29.2 to 29.8 days) However, there was a problem that accurate monthly phase data could not be obtained.

In addition, for example, when the battery driving the analog timepiece is exhausted and the rotation becomes incorrect and the battery is replaced, the correct moon phase or age at that time should be checked and set by the user. There was the inconvenience of having to fix it.

Although it is possible to realize the moon phase display function performed by such an analog clock with a digital clock, accurate moon phase data can be obtained only by counting the average cycle of the lunar sloppy movement with a counter. It is difficult to solve the problem that it cannot be obtained and that the setting of the monthly phase data at the time of battery setting is troublesome.

As the lunar movement, there is lunar movement in one day, that is, diurnal movement, in addition to the luster movement of the moon, which has a cycle of about one month as described above. There is a moon angle. The time angle of the moon means the angle between the time zone passing through the moon and the meridian, and the time angle of the midpoint of the moon with the meridian (South Central in the Northern Hemisphere) is 0 o'clock, and the meridian and the time zone of the moon are It represents the angle of westward rotation (0 ° to 360 °) from 0:00 to 23:00.

It is empirically known that the above-mentioned lunar phase and lunar angle affect the dietary activity of living things, and if the lunar phase and lunar angle are known, it is possible to use them for fishing and hunting. Although very convenient, there has been no electronic timepiece that optically displays the moon phase and the time angle of the moon.

[Purpose of device]

An object of the present invention is to provide an electronic timepiece that can optically display the moon phase and the time angle of the moon.

[Key points of device]

The present invention calculates the time angle data of the moon phase and the moon from the time information of at least the year, month, day, and time units and the position information, and calculates the time angle of the moon phase and the moon obtained by the calculation. The data is stored in the respective storage means, and the display signal for displaying the moon phase data and the hour angle data of the moon stored in the storage means is output.

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

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

The system is usually HALT in step S1 of FIG.
In the state, for example, the timekeeping process in the time unit of the minute unit or less in step S2 is executed every 16 Hz. In this time-count processing less than or equal to 1 minute, the time is measured in units of 1/16 second, second, and unit is 60 minutes.
When the minute is reached, the hour carry signal is output. And
In the next step S3, the presence or absence of the hour carry signal is determined. When the hour carry signal is generated, the flag F _{0 is set} to "1".
Set (S4). Here, the flag F ₀ is set to “1” because the time angle calculation of the moon, which will be described later, is performed on an hourly basis.

After that, the time unit timing process of step S5 is executed. As a result of the minute-by-minute timing processing (S2), if the hour carry signal is generated, 1 is added to the hourly data, and when the added time exceeds 24 hours, the daily carry signal is further added. Output.

Then, in step S6, it is determined whether or not there is a daily carry signal. When the daily carry signal is generated, the flag F ₁ is set to "1" (S7). Here, the flag F ₁ is set to “1” because the age calculation described later is performed on a daily basis.

Then, in the next step S8, the day, month, day of the week, and year counting processing are executed. In this day, month, day of the week, and year counting processing, the day of the week is changed if a day carry signal is generated, and 1 is added to the data in units of days. And as a result of the addition,
If a carry occurs on a monthly basis or on an annual basis, the time data for each month and year is further updated, and the updated time data is transferred to the time register X of the RAM 9.

When the time counting process is completed as described above, the process proceeds to step S9, and it is determined whether or not the flag F ₀ is set. If F ₀ = 0, that is, if the hour carry signal is not 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 is the calculation timing for calculating the hour angle of the moon every hour, and the moon angle calculation process of step S10 is executed.

The moon angle calculation processing 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, which is timed by the above-described timekeeping process, is converted to the Greenwich time based on the time difference data stored in the register B, and the Greenwich time is stored in the RAM 9 register
Store in Z ₀ .

Then, in the next step S22, a variable T for calculating the right ascension of the moon is calculated and stored in the register Z ₁ of the RAM 9 at the Greenwich side.

Here, the variable T is the number of days that have elapsed since January 1, 2000, 0:00 GMT (GMT = UT) and is the Julus century (3652).
(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) × CB−D + HO / 24 The variable T can be expressed by the following formula.

T = (Z-36556.5) / 36525 The variable T is calculated from this formula, and the calculated value is stored in the register Z ₁ of the RAM 9.

Next, in step S23, the Greenwich sidereal time at UT = 0 is obtained.

When Y = Z-25012, Greenwich sidereal time K can be expressed by the following equation.

K = 24 × FRAC (0.0027379 × Y) The Greenwich sidereal time is calculated from the above formula, and the calculated value is stored in the register Z ₂ of the RAM 9.

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

α = 32084.52539 x T +14.555441 +0.41925 x COS (477198.868 x T +44.963) +0.16358 x COS (962535.762 x T +166.633) +0.08494 x COS (413335.350 x T + 10.740) +0.07104 x COS ( 1934.140 × T + 324.960) + 0.07048 × COS (964469.900 × T + 41.590) + 0.04389 × COS (890534.220 × T + 145.700) It is represented by 24 × FRAC (α / 24).

Calculate the RA of the moon at UT = 0 o'clock from the above formula and calculate the value.
Stored in the register Z ₃ of RAM 9.

Next, UT in Greenwich is calculated from the Greenwich sidereal time and the visible RA of the moon obtained in step S25 as described above.
Calculate the hour angle of the month at 0:00.

Moon angle: JK can be calculated from the following formula.

The hour angle of the moon obtained from the above formula is stored in the register Z ₄ of RAM9.

Since the time angle of the moon at UT = 0 o'clock in Greenwich on the day is obtained as described above, the calculation for determining the time angle of the next day's month is performed.

First, in step S26, the date data of the time stored in the register Z ₁ is incremented by ₁ and stored in the register Zn, and similarly to step S22, the variable T of the next day that is incremented by 1 is calculated and stored in the register Z ₅ of the RAM 9. Store.

Next, as in step S28,29 At each step S23, S24, and calculates the viewing ascension of Greenwich sidereal time and the month in the time next day UT = 0, the register Z ₆ of those values RAM9 and Z ₇ It is stored in (S27, S28).

Then, in the next step S29, the UT at Greenwich on the following day is determined from the Greenwich sidereal time and the RA of the moon on the following day.
= Calculated angular time 0 month, and stores that value in register Z ₈ of RAM 9.

Since the time angle of the current day at UT = 0 o'clock in Greenwich and the time angle of the next day's month in Greenwich have been obtained by the above calculation, the lunar lunar day cycle of the month is calculated in step S30.

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

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

Calculate the lunar lunar day cycle from the above formula and store the value in the RAM9 register.
Store in Z ₉ .

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

For example, the angle of the moon at UT = 00: 00 in Greenwich is 3.8
h, assuming that the next day's UT = 0 hour moon angle is 3.1h, then DJK = 3.1h−3.8h = −0.7h.

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

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

The time when the hour angle is 0:00 can be expressed by the following formula.

In Greenwich, the time at which the hour angle of the month becomes 0 o'clock is obtained from the above formula, and the value is stored in the register Z ₁₀ of the RAM 9.

FIG. 8 is a chart showing an example of calculation at UT when the time angle is 0 o'clock.

For example, if the hour angle of the moon at UT = 0 o'clock is 3.8h, the time at which the angle becomes 0h is (24−3.8) × ( It can be calculated as 24.7 / 24) = 20.79 o'clock (20:47).

Returning to FIG. 6, from the time when the hour angle of the moon in Greenwich obtained at the above-mentioned calculation becomes 0:00, the next step S32
Then, the time when the time angle of the moon becomes 0:00 is calculated at a point being clocked or a designated point.

The time t at which the moon angle becomes 0 o'clock at an arbitrary point is calculated by the following formula.

Substituting the longitude and the time difference from Greenwich at the designated time point into the above formula, calculate the time at which the hour angle of the moon is 0 o'clock at that point, and store the time in register Z ₁₁ of RAM9. To do.

For example, in Tokyo at 139.75 degrees east longitude, the time t when the moon time is 0:00 is the time difference between Tokyo and Greenwich (+9 hours).
And the lunar lunar diurnal cycle (24.7
From UT time (20.79 o'clock) when the hour angle = 0 o'clock, it becomes as follows.

If the time at which the moon angle is 0 o'clock is obtained at the arbitrary point by the above calculation, then in step S33, the current time being measured or the moon angle at the specified time is calculated, and the register G of RAM9 is registered.
To store.

FIG. 9 is a chart showing an example of calculating the hour angle of the moon at 11:35 in Tokyo.

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

When the time difference is calculated by proportional calculation, the time difference = 24 x 8.62 ÷
24.7 = 8.38h. This time angle difference 0h (= 24
Subtracting from h), the hour angle of the moon at 11:35 = 15.62
We can find h.

That is, by designating the longitude of the arbitrary point and the time difference from Greenwich, it is possible to easily obtain the hour angle of the moon at the arbitrary time at the point by the above calculation.

If the calculation of the hour angle of the month is completed in this way, then the fifth
In step S11 in the figure, the flag F ₀ is reset 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 is set, that is, when the date is changed after 24 hours have passed, the process proceeds to step S13 to execute the age calculation.

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

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

Then, in step S42, the above-mentioned variable T is calculated from the Greenwich time.

Next, in step S43, the variable T obtained in step S42 is calculated.
From the following formula, calculate the visual longitude of the moon.

Lunar longitude = 481267.9 x T + 218.3 + 6.3 x COS (45 + 4572000 x T) + 1.3 x COS (11 + 413300 x T) Similarly, in the next step S44, from the variable T to Calculate the sutra.

Sun's visual longitude = 36000.8 × T + 280.5 + 1.9 × COS (268 + 36000 × T) From the difference between the moon's visual longitude and the sun's visual longitude, calculated in the next step S45. Find the separation angle of. The angle of separation of the moon is the angle between the sun and the moon as seen from the earth,
The lunar phase changes due to this change in the separation angle. For example, 0
When it is °, it is a new moon, when it is 180 °, it is a full moon, and when it is 270 °, it is the last moon.

Then, in step S46, the age of the moon is calculated from the above-mentioned lunar angle and the cycle of the lunar month. In this embodiment, the cycle of the lunar month is 29.53 days on average, and the age at the Greenwich time is calculated by proportional calculation from the cycle and the declination of the moon calculated every day. Then, the age of the point is calculated using the time difference between the point and Greenwich. That is, the age of the moon at any point can be expressed by the following formula.

FIG. 16 is a table for explaining the relationship between the lunar phase, the angle of departure of the moon, and the age of the moon, which is obtained by the above-described age calculation.

If the difference between the visual longitude of the moon and the visual longitude of the sun (angle of separation of the moon) obtained by the above calculation is, for example, in the range of 0 ° to 22.5 °, the age of the moon is 0.0 to 1.8 depending on the angle of separation. It becomes any value in the range of days, and the age data obtained at this time 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 moon's angle of departure is in the range of 157.5 ° to 202.5 °, the age of the moon will be any value in the range of 13.0 to 16.6 days, depending on the angle of departure at that time. Write to E. Ages 13.0 to 16.6 correspond to the full moon.

The same applies when the separation angle is in another angle range, and the relationship between the separation angle and the age of the moon and the lunar phase obtained by the calculation is as shown in the chart of FIG.

Returning to FIG. 5, when the age calculation is completed, the process proceeds to step S14, and the data flag F ₁ is reset to 0.

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

The fishing operation is to obtain the food activity data indicating the food activity of the animal from the lunar phase and the time angle of the moon, judge whether the current time is suitable for fishing and hunting, and display the suitability thereof. Is a calculation for displaying the four fish mark display bodies 2f.

FIG. 11 is a flowchart showing the contents of the phishing calculation in step S15.

First, in step ST1, obtain the moon phase data corresponding to the moon age obtained by the above-mentioned moon age calculation, and further, the moon phase data and the current time at the point during the timekeeping obtained by the above-mentioned moon time angle calculation. Obtain the fish mark number data to be displayed from the lunar angle data, and set it to 1 in register Z.
Make one remember.

Then, in the next step ST2, the above step ST1
The numerical value obtained by the above is stored in the register N that stores the number of fish marks displayed in the RAM 9. For example, if the current time is the most suitable time for fishing and hunting, the numerical value “4” is written in the register N, and if the second time is the most suitable time, the numerical value “3” is written in the register N.

FIG. 17 is a chart showing the relationship between the number of fish marks displayed on the display unit 2 and the lunar phase and the hour angle of the moon as a result of the above-mentioned phishing calculation.

For example, when it is a new moon or a full moon, and the time angle of the moon is 0 o'clock or 12 o'clock, it is the most suitable time for fishing and hunting.
The value obtained by the calculation of 1 is “4”, and the step S
At T2, "4" is written in the register N. As a result,
Four fish marks are displayed on the display unit 2 by the display process of step S16 of FIG. 5 described later.

It is also suitable for fishing and hunting in the new moon or full moon, when the moon angle is 6 o'clock or 18 o'clock, or when the moon angle is 0 or 12 o'clock in the upper or lower strings. When the moon phase and the moon angle match the above condition, "3" is written in the register N. As a result, the display unit 2
Is displayed with three fish marks.

In addition, with the new moon or full moon, the hour angle of the moon is 0:00, 12:00, 6
At times other than 18:00, it is the third time suitable for fishing and hunting, "2" is written in the register N, and two fish marks are displayed on the display unit 2.

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

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

Returning to FIG. 5, if the phishing calculation in step S15 is completed, then the display processing in step S16 is executed. In this display processing, various data obtained by the above-described time counting processing, moon angle calculation, moon age calculation, and fishing calculation are displayed.

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

First, in 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, the time data stored in the current time register X is transferred to the display register A ₄ in the next step S52.

Further, in the next step S53, the moon phase data to be displayed is calculated from the moon age data stored in the register E and stored in the display register A ₁ .

In the present embodiment, the moon phases are displayed in nine stages, which of the nine phases is judged from the age data, and the corresponding moon phase indicator 2a is designated "1-9". The numerical data of is written in the display register A ₁ as monthly phase data. 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, from the time angle data stored in the register G, data designating any one of the time angle display bodies 2c of 0 to 23:00 of the display unit ₂ is written in the display register A2.

For example, if the hour angle of the month stored in the register G is 0:00, the numerical value “0” is written in the display register A ₂ ,
The hour-angle indicator 2c located above the printed numerical value "0" lights up. Below, with the change of the hour angle data, the numerical value that is sequentially incremented is written in the display register A ₂ ,
The bar-shaped hour-angle indicator 2c sequentially lights in a clockwise direction.

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 above-mentioned display registers A ₁ , A
₂ , A ₃ A ₄ display moon phase data, hour angle data, fish mark data, and time data stored in A ₄ are displayed on the display unit 2.

Unless M = 0 in the mode determination in step S51,
In step S57, it is determined whether the mode register M is "1".

If the correction mode is M = 1, it is determined in the next step S58 whether the value of the register P is P = 0 to 5. P = 0 to
If any of 5 is, it means that one digit of the month, the day, the day of the week, the hour, the minute, and the second is the digit to be corrected, and the step S59 is performed.
Then, the month, sunday, hour, minute and second data of the current time register X is transferred to the display register A ₄ and the digit to be corrected is displayed in blinking.

In the determination of step S58, if P = 0 to 5 is not satisfied,
Next, in step S60, it is determined whether P = 6. P = 6
If so, it means that the year digit is the digit to be corrected, and step S61 is performed.
Then, the month, day, day of the week and year data of the current time register X are transferred to the display register A ₄ and the data are displayed.

If P = 6 is not found in the determination in step S60, the process proceeds to step S62. That is, when P = 7, 8 or 9, it is time to set the time difference from the Greenwich at the point where you want to know the monthly data, the longitude and the latitude, and the character data that indicates the type of input data according to the value of P at that time. (GMT, LO
Etc.) and the time difference, longitude and latitude data of registers B, C and D of RAM9.

If M = 1 is not found in the determination in step S57,
Judged to be the display mode of sunrise / sunset time of M = 2,
In step S63, the display register A ₀ is set to "1".

Then, in the next step S64, the moon phase data for display is calculated from the moon age data of the register E, and the data is transferred to the display register A ₁ .

Further, in the next step S65, based on the date data and the time difference data, the sunrise and sunset time data of the area having the time difference is read from the ROM 11 and transferred to the display register A ₄ to display those data.

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

This key processing will be described in detail based on the flowchart of FIG.

First, in step S71, it is determined whether or not the operated key is the K1 key. If it is the operation of the K1 key, it is determined in the next step S72 whether or not the value of the mode register M is "0". If M = 0, it means that the K1 key is operated in the time display mode, and "0" is set in the register P in the next step S73. The reason why "0" is set in the register P is that the digit to be corrected starts from the second digit of P = 0 when the correction mode is switched to.

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

If M = 0 is not determined in the determination in step S72,
In step S75, it is determined whether M = 1. M = 1
If so, it means that the K1 key has been operated in the correction mode, and in the next step 76, the above-described calculation of the hour angle of the moon, the calculation of the age of the moon, and the fishing calculation are executed. And the next step
In S77, "0" is set in the mode register M to switch from the correction mode to the time display mode.

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

If it is not the operation of the K1 key in the determination of step S71,
In step S78, it is determined whether the K2 key is operated. K
If it is a 2-key operation, it is further determined in the next step S78 whether or not the value of the mode register M is "0". If M = 0, the register M is set to "2" in the next step S79 and the sunrise is performed. / Switch to sunset time display mode.

If M = 0 is not found in the determination in step S78,
Next, in step S80, it is determined whether or not the value of the mode register M is "2". If M = 2, "0" is set in the register M in the next step S81 to switch to the time display mode.

FIG. 14 is a diagram showing the transition of the 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 moon phase at that time, the time angle of the month, and the fish mark, if any, are displayed.

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, sunrise /
In the sunset time display mode, the sunrise / sunset mark indicator 2b lights up and the dot display 2g of the display unit 2 shows the age of the moon (in FIG. 14, the age of the moon) along with the moon phase and the time angle of the moon.
22.4 days), the upper segment display body 2h displays the sunrise time (also 5:25), and the lower segment display body 2i displays the sunset time (also PM 8:35).

Returning to FIG. 12, if the K2 key is not operated in the determination of step S78, the process proceeds to step S82 and it is determined whether or not the K3 key is operated.

If the operated key is the K3 key, it is further determined in step S83 whether the value of the mode register M is "1", and M =
If it is 1, the register P is incremented in step S84.

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 S82 that the K3 key is not operated,
In step S85, it is determined whether the K4 key is operated.

If the operated key is the K4 key, it is determined in step S86 whether or not the value of the mode register M is "1". If M = 1, in the next step S89, the correction digit designated by the register P Perform processing to correct data.

Furthermore, if the K4 key is not operated in the determination in step S85, it means that the K5 key or the K6 key is operated, and the process proceeds to step S90 to execute other key processing.

FIG. 15 is a display state diagram showing an example of time correction and input of time difference, longitude, and latitude in the correction mode. When you switch to the correction mode by operating the K1 key from the time display mode, the date, day of the week and time are displayed as shown in Fig. 15 (1), and the second digit blinks first and the second digit can be corrected. Become.

After that, 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 digit, and each digit blinks, and the K4 key enables the amendment. When the K3 key is operated again in this state, as shown in FIG. 15 (2), the year data blinks at the digit where the second data was displayed, and the year digit data can be corrected.

If you further operate the K3 key in this state, the dot display body 2g
The character "GMT" flashes on the display, and the segment display 2h on the right side of that also flashes, and the time difference from GMT can be entered by pressing the K4 key. FIG. 15 (3) shows the display state when the time difference of BMT and New York daylight saving time-4 hours is input.

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

Further, when the K3 key is operated, the character "LR" indicating the latitude of the dot display body 2g is blinkingly displayed, and the segment display body 2h on the right side is blinkingly displayed so that the latitude can be input. FIG. 15 (5) shows a display example when the latitude of 41 ° in New York is input.

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

As described above, since the moon phase and moon angle data are calculated from the clocked time and position information as described above, accurate lunar movement data and lunar diurnal movement data are displayed. can do.

Also, even when replacing the battery of the power supply of the electronic timepiece, the correct moon phase and moon time angle data can be obtained again simply by inputting the position information such as longitude and latitude. It is extremely convenient because you do not have to correct the lunar phase data yourself.

In the above embodiment, the user can arbitrarily set the position information for calculating the lunar phase and the moon angle data, but in order to simplify the operation, the position information specific to You may memorize it.

Furthermore, in the above-mentioned embodiment, since the timed time is temporarily changed to the time of Greenwich, the month data in Greenwich is obtained, and the month data of the point during timekeeping is obtained from the month data of Greenwich. It is possible to simplify various calculation processes such as time angle calculation.

Further, in the above embodiment, the current time is used as the time data, and the position information is set by the K4 key.
It is also possible to input time data and position information using a ten-key pad, a keyboard provided with a time input key, a position key, or the like, and calculate month data based on the input data.

Further, the calculation timing of the age of the moon, the time angle, etc. is not limited to the unit of one day or one hour as in the present embodiment, and the calculation may be performed at a shorter time interval, for example, the time angle of the moon every one minute. May be calculated.

On the earth, the moon is almost invisible between about 7:00 and 17:00, so for example, as shown in Fig. 18, the display units 2C _{0 to} 2C ₁₃ are provided and the hour is from 18:00 (true east). Display up to 6 o'clock (true west) with any of the display bodies 2C _{1 to} 2C ₁₃ (display body 2C ₇ at 0 o'clock time), and wait between 7 o'clock and 17 o'clock hours. For example, the display 2C ₀ may be displayed only when the hour angle is 12:00, and the others may not be displayed. Then, if the east and the west are respectively printed and displayed as shown in FIG. 18, for example, E and W, it is possible to immediately know in which direction the moon is viewed. Further, the display of the above-mentioned moon phase and time angle may be displayed in black on a white background by a liquid crystal display, or may be displayed in a black character so as to be blank.
Furthermore, if the display is performed in color, the design will be extremely excellent.
