Leap year calendar is a feature that is found on some watches that allows the user to keep track of the calendar year with an additional day added to the calendar every four years. This feature allows the wearer to more easily keep track of the current year, as well as to plan ahead for special events or occasions that fall on a leap day. With this feature, the user will be able to view the date for a full four year cycle, rather than just for a single year.
