Abstract (en)
[origin: EP0400542A2] An astronomical data indicating device is provided with a memory (D, H) for storing location data representing a location on the earth. In the present device, before calculation of astronomical data such as hour angle data of moon and moon phase data, in steps (S32, S33), a first hour angle data and moon phase data for Greenwich Mean Time are calculated regardless of the place where the present device is used, and then hour angle data and moon phase data at the place where the present device is used are calculated. Therefore, the calculation process is performed in a very simple manner.
