February 29 is indeed a signature of a leap year, occurring every 4 years to keep our calendar in alignment with the Earth's revolutions around the Sun. However, not every year divisible by 4 is a leap year; years divisible by 100 are not leap years unless they are also divisible by 400. Thus, February 29 only takes place in years that satisfy these conditions, making leap years a special occurrence.
