Abstract
PURPOSE: To make it possible to preset a special day and for a user to reliably know that special day by providing a counting circuit unit having at least one counting circuit, a special day presetting circuit and a coincidence judging circuit unit.
CONSTITUTION: In addition to a first counter 2 for counting normal time and month and day and to first coincidence judging circuit 6 for comparing the content of the counter w with an alarm time memory 7, there are also provided a second counter 8 and a second coincidence juding circuit 9 for comparing the content of a special day presetting memory 10. The coincidence signals Sl of the circuit 9 are at an L level for one day preceding the special day. A thired coincidence judging circuit 11 compares the contents of the first conter 2 and a special day presetting memory 10 so that its coincidence signals Sm are at the L level for the special day. An alarm control circuit 12 selects four kinds of warning sounds such as the time informing sounds of the normal day, the day preceding the special day, and that special day or the alarming sounds of the normal time, thereby to control a buzzer drive circuit 13
