Balclutha resident De Reece Kupa-Pickering is only 4 years old, but has already finished university and worked overseas.
That is because he only officially celebrates his birthday every four years.
He is one of a small number of people born on February 29.
While a usual year has 365 days, a leap year has 366, and the extra — or intercalary — day is designated to the end of February.
Mr Kupa-Pickering is really about to turn 20, but said it would be “very cool” to celebrate his fifth birthday on February 29.
He said he never wished he had a different birthday. “I didn’t really get it when I was growing up, but as I got older I thought it was awesome and pretty unique.”
He used to celebrate his nonleap year birthdays on March 1, but eventually decided to shift it to February 28 “to get the presents sooner”.
“I don’t usually do much for my birthdays these days, so I try to go big on the leap year ones,” he said.
The former University of Otago student had a large celebration planned with friends and family in Dunedin for his birthday next week.
