Twelve more than just a birthday
Maths is one of Piper Mortimer's favourite subjects and that is probably why she is looking forward to tomorrow more than most people.
Piper will turn 12 tomorrow, December 12, or 12.12.12.
She has been anticipating her special birthday on the unique day for some years and says the number 12 has always been her favourite.
"When we play sports and get to pick a number I always try to pick 12," she says.
The year 7 Kamo Intermediate School student plays hockey for her school, swims and is learning to play the keyboard.
She also does some Samoan dance because her grandmother comes from the Pacific island.
Piper had a birthday celebration with her friends on Saturday but will be having a big barbecue with her extended family tomorrow.
She is not sure if she should expect any extra presents because of the special day.
"My parents are going to fix my iPod which has cracked - other than that I'm not sure," she says.
Worldwide over 300,000 young people will be sharing Piper's 12.12.12 birthday.
There have been a string of special birthdays for Whangarei children over the past few years.
Last year two Whangarei youngsters celebrated their 11th birthday on 11.11.11 - rugby-mad Jake Weatherall and budding actress Tove Patersson.
In 2010 Hurupaki School student Olivia Coop marked her 10th birthday on October 10, or 10.10.10.
