Tomorrow is February 29. You probably don’t know anyone who was born on this date because they are very rare. February 29 only comes once every four years. We call that year a leap year, and the people who are born on February 29 are called leapers. I read that there are only 5 million leapers in the world! You may think that leapers are unlucky because they only have a birthday once every four years, but that isn’t really true. In a regular non-leap year, they celebrate their birthday either on February 28 or March 1. In a leap year, however, leapers have a really big celebration for their true birthday!
