PURPOSE: To display a precise worship time even in any area on the earth in, for example, a worship time display device for Islam. CONSTITUTION: Of six solar position data necessary for the calculation of a worship time, each solar position data of FAJR, ASR, ISHA different every area is stored in a ROM 16 as systems '0'-'7' consisting of seven kinds of combinations. When the area position data (difference in time, latitude, longitude) of a using area and a prescribed worship time of the area, 'JAJR', 'ASR', 'ISHA' are inputted, they are set in each resistor in a RAM 17. The system number showing the solar position data corresponding to this area is selectively judged on the basis of the area position data and the prescribed worship time data. Thereafter, each worship time (FAJR, RISE, ZOHR, ASR, MGRB, ISHA) of that day is calculated on the basis of the area position data, the solar position data shown by the selected system number, other fixed solar position data, and the A.D. date, and displayed on a display part 19. |
