As the day comes every four years, it means those born on February 29 miss out on birthdays

With the chance of babies being born on a leap day at one in around 1,500, there are an estimated five million leaplings in the world today, as per BBC

Even though “leapers” pick another date to make sure they have an annual birthday, their age is technically younger than most
In the UK, people born on this day are also required to have their birth date to be officially listed on either February 28 or March 1

As per UK law, when a child is born on a leap day, the official birthday is actually on February 28 when it is a non-leap year

Some of the famed or notorious leaplings are Spanish Prime Minister Pedro Sanchez, US rap star Ja Rule and serial killer Aileen Wuornos

Earth takes a bit more than 365 days to complete its dance around the Sun. So, every four years, we add an extra day, called leap day, to make sure our calendars match the sky
