An electronic timepiece with date display function reduces power consumption
in
conjunction with the user adjusting the date, and makes it easier for the user
to set the date. A displayed date detection unit H has a day detector H1
for detecting the displayed day, a month detector H2 for detecting the displayed
month, and a year detector H3 for detecting the displayed year. A control
unit A controls a calendar mechanism drive unit F according to the date detected
by detectors H1 to H3.
