Every four years is a leap year. Leap years add one extra day to February due to an astronomical fact that the earth’s revolution around the sun equals 365.25 days not 365.00 like the Gregorian calendar follows. The probability of a leap day birthday is 1/1461, therefore, a leap day birthday on February 29 is the least probable of all birthdays. This means that less than 0.07% of the world’s population was born on a leap day.
