- Still another embodiment may be constructed such that moon data for one month or for one week are calculated at the beginning of month or week and the results are stored in memories, and then the calculated moon data are successively displayed as time lapses.
- the fish catch forecasting is indicated with the four fish mark indicating elements but number of the indicating elements may be increased for more precise indication or digital indicating means may be employed to indicate times for fishing in percent, such that the best time for fishing is expressed with "100%".
- Figs. 19 to 22 are views illustrating yet another embodiment of the present invention. This embodiment will be described hereafter with reference to only its portions different from the above described first embodiment shown in Figs. 1 through 18.
- the process of Fig. 19 includes an additional operation of Step T1 for obtaining data to indicate an expected fish catch volume after Step S10 in the whole processes of Fig. 5.
- Step T1 number of fish mark indicating elements to be turned on is calculated at Step T2 from present hour angle of the moon and moon phase or moon's age, and the result is stored in a register Z.
- Step T3 the data stored in the register Z is transferred to a register Q0.
- the fish mark indicating elements stored in the register Q0 are displayed in the present time indicating mode.
- Step T2 in Fig. 20 for obtaining number of the fish mark indicating elements is as shown in Fig. 21 and different numbers of fish mark indicating elements are obtained by combining moon phases and hour angles of the moon other than those at 0h, 6h, 12h and 18h in addition to the table shown in Fig. 17.
- the embodiment which is capable of indicating expected fish catch volume together with the present time may be provided with a feature which functions to generate an alarm when the best time for fishing is reached or when all of the fish mark indicating elements 2f are turned on. Further, the embodiment may be provided with a feature which functions to generate different alarm sounds each time when the expected fish catch volume is changed.
- time difference from GMT, longitude and latitude are set, but a world watch is well known which is capable of indicating cities around the world as well as the times at these cities and the present invention may be applied to this type of watch, thereby indicating moon data for these cites.
- New York is at 74 degrees of longitude and 41 degrees of latitude and the time difference from GMT is minus 5 hours.
- still another embodiment may be constructed such that longitude data, latitude data and time difference from GMT for various cities are stored, for example, in ROM, and when, for example, New York is designated on the world watch and time at New York is indicated, hour angle of the moon, moon phase, sunrise time and sunset time are calculated from the data stored in ROM and the present time at New York, and these data thus calculated are displayed.
- a world watch may be constructed such that longitude data and latitude data for various cities are displayed, and these data are changed, and thereby moon data for an area in the vicinity of these cities are obtained.
- the present invention is not limited to the above embodiments but may be used in various manners, and may be also used to obtain locations of various planets other than the moon or locations of fixed stars.
