Once set the calendar automatically adjusts for odd and even months including February of leap years to February 28, 2100. When the watch senses 24 hours of inactivity it puts itself into suspended animation (sleep mode) to conserve energy. The date continues to advance correctly while the watch is "asleep". Wake it up with a few shakes of your wrist and it automatically resets itself to the correct time, even if it has been asleep for 4 years.
