Abstract

A salat time alarm electronic timepiece is implemented with a one chip microcomputer. An outer read only memory is installed in the electronic timepiece for storing the sunrise time data and the sunset time data at various cities in world. The system reads out sunrise time and sunset time data from the outer read only memory and calculates five salat times of the present day. The thus calculated salat time data is stored in a storage means and compared with the current time data to provide an alarm sound when the current time reaches one of the five salat times.
