About This Answer
Leap years have 366 days, adding an extra day to February to keep the calendar synchronized with Earth's orbit. According to NASA astronomers, Earth's actual orbital period is 365.2422 days, necessitating the leap year correction. The U.S. Naval Observatory documents how Julius Caesar introduced leap years in 45 BCE. Modern calendar systems use the Gregorian rule: years divisible by 4 are leap years, except century years must be divisible by 400. The 366-day leap year represents humanity's mathematical solution to astronomical reality.
