PURPOSE: To ensure the confirmation of arrival of specific day with listening to the alarm tone produced differently from other days at the specific day set and stored.

CONSTITUTION: When the specific day set in the calendar memory circuit 11 is in agreement with the present day in response to the count of the calendar count circuit 7, the AND gates 13a, 13c are closed via the coincidence circuit 8 and the AND gates 13b, 13d are opened. Thus, the alarm tone and time casting tone different from those produced with the time alarm production circuit 14 and time casting tone production circuit 16 are generated at the dates other than the specific day via the time alarm generating circuit 15 and the time casting tone generating circuit 17, allowing to ensure the confirmation of the arrival to the specific day not by visual observation but by listenning.
