4-year calendar
A 4-year calendar, is a type perpetual calendar complication found in some wrist watches, that automatically takes into account the varying lengths of the months. This means that the calendar only needs to be adjusted once every four years, on leap years. A 4-year calendar will typically display the date, day of the week, month, and sometimes the moon phase. This feature is considered to be a highly complicated, due to the number of moving parts and level of precision required to accurately track and display the various calendar elements.
