PURPOSE:To provide a time-display device wherein it is convenient for both a person wondering large cities one after another and a person settled down in a small city in the country and it is provided with a worship-time display function. CONSTITUTION:The time display device is constituted so as to be controlled by a CPU 1. The time difference, the latitude, the longitude and the like of specific cities, i.e., main large cities in the world, are stored fixedly in advance in a ROM 6, and the time difference, the latitude, the longitude and the like of cities which are arbitray to a user (i.e., arbitrary cities) can be stored in a RAM 7. When any specific city or any arbitray city is selected by a switch at a switch part 9, the time difference and the like of the city are read out from the ROM 6 or the RAM 7, and the worship time is computed on the basis of them and displayed. |
