Abstract
An electronic timepiece circuit for automatically changing the day of the week by utilizing the timekeeping signals produced by the day counter, month counter and year counter is provided. Remainder circuitry is coupled to the respective day, minute and year counters and is adapted to sum bit signals representative of the binary count of the respective day, month and year counters and divide the summed bit signals by a count of seven and thereby produce a remainder signal. The remainder signal is applied to appropriate decoding and display circuitry to effect a display of the day of the week in response to the remainder signal applied thereto.
