Feb. 29 is rare because it only occurs every four years in a leap year. A normal year has 365 days, but the Earth actually takes about 365.24 days to orbit the Sun. To align our calendar year with the Earth's orbit, an extra day, Feb. 29, is added approximately every four years, compensating for the extra 0.24 days per year.
