A Leap Day, February 29, is added to the calendar during leapyears. This extra day, also called Leap Year Day, makes the year 366 days long – not 365 days, like a commonyear.
Leap days are needed to keep our calendar in alignment with the Earth's revolutions around the Sun.

Without an extra, or intercalary day on February 29 nearly every four years, we would lose almost six hours every year. After only 100 years, a calendar without leap years would be off by approximately 24 days. Seasonal days such as the vernal equinox or the winter solstice would, therefore, shift in relation to the months in the calendar. For example, in 100 years, the Northern Hemisphere's autumnal equinox, which falls in late September, would fall in late August, and in a few centuries, August would become a spring month.
