Leap year

A leap year is where we have one extra day in the year. We have a leap year every four years. This year we have a leap year. A year without the leap year is called a common year, the day of the leap year is called leap day. A person born on a leap day would be called a "leapling" or a "leaper". People would usually celebrate their birthday on February 28th , Or March 1st. I would celebrate it on February 28th. If I was born on a leap day I would really only be 3 years old. That would be weird and unique.
