A mode selection switch is provided for selectively enabling a time information display, namely, a timepiece mode, and a calculator operation, namely, a calculator mode. Function keys for the calculator operation are adapted to select a desired time information section, for example, the date information section, the hour information section, and the minute information section during the timepiece mode, thereby resetting the time information stored in the selected information section to zero. Thereafter, a desired value is introduced into the selected information section through numeral keys for the calculator operation. If the timepiece mode is selected, a separate key selects either hours/minutes/seconds or days of the week. The days of the week are displayed on a decimal point indicator display. Another separate key will correct the indication on the decimal point indicator display to display the correct day of the week once the days of the week are selected by the above mentioned separate key. The decimal point indicator display may also function to display the numerical decimal point in the calculator mode.
