A "leap year" is a year that contains more days than other years (for solar or lunar calendars) or more months than other years (for lunisolar calendars like Hebrew or Chinese).
Some calendars, especially lunisolar ones, have further variation in year length that is not represented in the output of this operation (e.g., the Hebrew calendar includes common years with 353, 354, or 355 days and leap years with 383, 384, or 385 days).
